Amy Jean Klobuchar (; born May 25, 1960) is an American lawyer and politician serving as the senior United States senator from Minnesota. A member of the Minnesota Democratic-Farmer-Labor Party, Minnesota's affiliate of the Democratic Party, she previously served as the Hennepin County Attorney. She ran for the Democratic nomination for President of the United States in the 2020 election, before pulling out in March and endorsing Joe Biden.

Klobuchar's political positions have generally been in line with modern American liberalism. She is pro-choice on abortion, supports LGBT rights and the Affordable Care Act, and was critical of the Iraq War.

According to GovTrack, Klobuchar passed more legislation than any other senator by the end of the 114th Congress in late 2016. According to Congress.gov, , she had sponsored or co-sponsored 111 pieces of legislation that became law. During the 115th Congress, she voted in line with President Donald Trump's position on legislation 31.1 percent of the time.

Crime Criminal justice reform In December 2018, Klobuchar voted for the First Step Act, legislation aimed at reducing recidivism rates among federal prisoners through expanding job training and other programs in addition to forming an expansion of early-release programs and modifications on sentencing laws such as mandatory minimum sentences for nonviolent drug offenders, "to more equitably punish drug offenders."

On July 31, 2019, following Attorney General William Barr announcing that the United States federal government would resume the use of the death penalty for the first time in over 20 years, Klobuchar was a cosponsor of a bill banning the death penalty.

Gun laws As of October 2018, Klobuchar has an "F" grade from the National Rifle Association Political Victory Fund (NRA-PVF) for supporting gun control legislation.

In the wake of the 2016 Orlando nightclub shooting, Klobuchar participated in the Chris Murphy gun control filibuster.

Following the Las Vegas shooting in October 2017, Klobuchar was one of 24 senators to sign a letter to National Institutes of Health (NIH) Director Dr. Francis Collins espousing the view that it was critical the NIH "dedicate a portion of its resources to the public health consequences of gun violence" at a time when 93 Americans die per day from gun-related fatalities and noted that the Dickey Amendment did not prohibit objective, scientific inquiries into shooting death prevention.

In November 2017, Klobuchar was a cosponsor of the Military Domestic Violence Reporting Enhancement Act, a bill that would form a charge of Domestic Violence under the Uniform Code of Military Justice (UCMJ) and stipulate that convictions would have to be reported to federal databases with the authority to keep abusers from purchasing firearms within three days in an attempt to close a loophole in the UCMJ through which convicted abusers retained the ability to purchase firearms.

In January 2019, Klobuchar was one of 40 senators to introduce the Background Check Expansion Act, a bill that would require background checks for either the sale or transfer of all firearms including all unlicensed sellers. Exceptions to the bill's background check requirement included transfers between members of law enforcement, loaning firearms for either hunting or sporting events on a temporary basis, providing firearms as gifts to members of one's immediate family, firearms being transferred as part of an inheritance, or giving a firearm to another person temporarily for immediate self-defense.

In February 2018, after the Stoneman Douglas High School shooting, Klobuchar was one of four Democratic senators to sign a letter to President Trump asserting that were he "to endorse legislation to require a background check on every gun purchase, without other poison pill provisions attached, we could finally move much closer towards the comprehensive system that you called for after the Stoneman Douglas attack" and that there was no justification in allowing individuals denied firearms by federally licensed dealers being able to "simply visit a gun show or go online to purchase the same gun that they were denied at the store."

In February 2019, Klobuchar was one of 38 senators to sign a letter to Senate Judiciary Committee Chairman Lindsey Graham calling on him to "hold a hearing" on universal background checks and noted Graham's statement in the press that he "intended to have the Committee work on ‘red flag’ legislation and potentially also background checks", actions the senators indicated their support for.

In May 2019, as Senate Democrats pressured Senate Majority Leader Mitch McConnell to allow a vote on a bill to renew the Violence Against Women Act, which included an amendment closing the "boyfriend loophole" which barred those convicted of abusing, assaulting or stalking a dating partner from buying or owning a firearm, Klobuchar advocated for the Senate passing the bill and called the measure crucial to protect women in the United States who died from gun violence at larger rates there than in other high-income countries.

At the Detroit Democratic debate on July 31, 2019, Klobuchar invoked the death of 6-year-old Stephen Romero in the Gilroy Garlic Festival shooting and noted that President Trump supported background checks in a meeting before changing his position following a separate meeting with pro-gun group before stating that she would not fold if elected president and would secure the passage of universal background checks.

Crime control According to her Senate website, while serving as Attorney of Hennepin County, Klobuchar was "a leading advocate for successful passage of Minnesota's first felony DWI law". (official Senate webpage, 2013) She also focused on the prosecution of violent and career criminals while serving as County Attorney.

Eric T. Schneiderman, the New York State Attorney General, praised Klobuchar's efforts for legislation against phone theft. In 2017 she took over sponsorship from Al Franken of a bill to provide grants for law enforcement personnel to receive training in how to question survivors of sexual assault and other trauma, after Franken was accused of sexual misconduct.

In 2011, Klobuchar introduced S.978, the Commercial Felony Streaming Act, a bill that would make unauthorized streaming of copyrighted material for the purpose of "commercial advantage or personal financial gain" a felony under US copyright law. Backed by the U.S. Chamber of Commerce and praised by industry groups, the legislation has been enormously unpopular among critics who believe it would apply to those who stream or post videos of copyrighted content on public sites such as YouTube.

Economy Agriculture In March 2018, Klobuchar and Republican John Thune introduced the Agriculture Data Act, a bill that would direct the Secretary of Agriculture "to collect, collate, integrate, and link data relating to the impacts of covered conservation practices on enhancing crop yields, soil health, and otherwise reducing risk and improving farm and ranch profitability" in addition to granting the Agriculture Secretary the ability to form a data warehouse on the subjects of confidential cloud-based conservation and farm productivity that would reserve records of multiple analysis. Klobuchar stated that the bill would "ensure hardworking farmers are able to capitalize on the United States Department of Agriculture’s vast resources to streamline their operations, enhance yields, and increase profits."

In March 2019, Klobuchar was one of 38 senators to sign a letter to Agriculture Secretary Sonny Perdue warning that dairy farmers "have continued to face market instability and are struggling to survive the fourth year of sustained low prices" and urging his department to "strongly encourage these farmers to consider the Dairy Margin Coverage program."

In May 2019, Klobuchar was one of nine Democratic senators sent a letter to Perdue in which they criticized the USDA for purchasing pork from JBS USA and wrote that it was "counterproductive and contradictory" for companies to receive funding from "U.S. taxpayer dollars intended to help American farmers struggling with this administration's trade policy." The senators requested the department "ensure these commodity purchases are carried out in a manner that most benefits the American farmer’s bottom line—not the business interests of foreign corporations."

Company mergers and regulations In February 2019, Klobuchar was one of eight senators to sign a letter to the Federal Communications Commission and Department of Justice advocating for regulators to reject a proposed $26 billion merger between T-Mobile and Sprint, writing that American enforcers have understood for the last 30 years "that fostering robust competition in telecommunications markets is the best way to provide every American with access to high-quality, cutting-edge communications at a reasonable price" and the merger would result in a return for "Americans to the dark days of heavily consolidated markets and less competition, with all of the resulting harms."

In March 2019, Klobuchar was one of six senators to have signed a letter to the Federal Trade Commission (FTC) requesting it "use its rulemaking authority, along with other tools, in order to combat the scourge of non-compete clauses rigging our economy against workers" and espousing the view that non-compete clauses "harm employees by limiting their ability to find alternate work, which leaves them with little leverage to bargain for better wages or working conditions with their immediate employer." The senators furthered that the FTC had the responsibility of protecting both consumers and workers and needed to "act decisively" to address their concerns over "serious anti-competitive harms from the proliferation of non-competes in the economy."

In June 2019, Klobuchar led six other Senate Democrats in signing letters to the FTC and the Department of Justice recounting that many of them had "called on both the FTC and the Justice Department to investigate potential anticompetitive activity in these markets, particularly following the significant enforcement actions taken by foreign competition enforcers against these same companies" and requested both agencies confirm whether or not opened antitrust investigations had been opened by them regarding each of the companies and for both agencies to pledge they will publicly release any such investigation's findings.

Housing In April 2019, Klobuchar was one of 41 senators to sign a bipartisan letter to the housing subcommittee praising the Housing and Urban Development Departments's Section 4 Capacity Building program as authorizing "HUD to partner with national nonprofit community development organizations to provide education, training, and financial support to local community development corporations (CDC's) across the country" and expressing disappointment that President Trump's budget "has slated this program for elimination after decades of successful economic and community development." The senators wrote of their hope that the subcommittee would support continued funding for Section 4 in Fiscal Year 2020.

Labor laws In July 2019, Klobuchar signed a letter to Secretary of Labor Alexander Acosta that advocated for the U.S. Occupational Safety and Health Administration to initiate a full investigation into a complaint filed on May 20 by a group of Chicago-area employees of McDonald's, which detailed workplace violence incidents that included interactions with customers such as customers throwing hot coffee and threatening employees with firearms and more. The senators argued that McDonald's could and needed to "do more to protect its employees, but employers will not take seriously their obligations to provide a safe workplace if OSHA does not enforce workers rights to a hazard-free workplace."
