Roger Frederick Wicker (born July 5, 1951) is an American politician, attorney, and Air Force veteran serving as the senior United States senator from Mississippi, a seat he has held since 2007.

Wicker served in the House from 1995 to 2007, when he was appointed to the Senate by Governor Haley Barbour to fill the seat vacated by Lott.

[12] In the general election, Wicker defeated Fulton attorney Bill Wheeler, 80,553 votes (63.06%) to 47,192 (36.94%),[13] making him the first Republican to represent the 1st district in over a century.

[16] In 2007, Wicker was criticized after securing a $6 million earmark for a defense company whose executives had made significant contributions to his campaign.

[19] Wicker ran for the remainder of Lott's term in the November 2008 special election against Democrat Ronnie Musgrove, Barbour's predecessor as governor.

He was opposed by Robert Maloney and Tea Party activist E. Allen Hathcock in the Republican primary, defeating them by 254,936 votes (89.17%) to 18,857 (6.60%) and 12,106 (4.23%), respectively.

Wicker called the Affordable Care Act the "great fight for the rest of this term, maybe our lifetimes" and later introduced a bill to enable state officials to challenge the law.

In the interest of protecting gun owners, he amended a fiscal 2010 transportation spending bill to allow Amtrak passengers to carry firearms and ammunition in checked baggage.

[27] Wicker and Representative Gene Taylor pushed amendments allowing purchasers of federal flood insurance to add wind coverage to their policies, helpful to a hurricane-prone state.

The measure led Russian President Vladimir Putin to announce a subsequent ban on U.S. adoptions of Russian-born children.

Wicker said he hoped the chamber's bipartisan past could serve as an inspiration for the debate about the nuclear option: "I think there are concessions that can be made on both sides.

"U.S. should stand steadfast with the people of Hong Kong in their fight to exercise self-determination," Wicker said, and "speak with a unified American voice in support of universal freedom and democratic values.

The Congress and the Obama Administration should act to ensure China honors its longstanding obligation under international law to maintain Hong Kong's autonomy.

[37][38] In May 2020, a group of Senate Republicans planned to introduce a privacy bill that would regulate the data collected by coronavirus contact tracing apps.

The act would permit the creation of "platforms that could trace the virus and help flatten the curve and stop the spread – and maintaining privacy protections for U.S. citizens", Wicker said.

[39] In September 2020, less than two months before the next presidential election, Wicker supported an immediate Senate vote on Trump's nominee to fill the Supreme Court vacancy caused by Justice Ruth Bader Ginsburg's death, saying that Senate Republicans had "promised to confirm well qualified, conservative judges" and that there was a "constitutional duty" to fill vacancies.

[42] In the wake of the violence and certification, Wicker called for perpetrators to be prosecuted "to the fullest extent of the law" and said, "we must work together to rebuild confidence in our institutions.

[44] In March 2021, after Congress passed the American Rescue Plan Act of 2021, Wicker highlighted on social media that the bill awarded $28.6 billion of "targeted relief" to "independent restaurant operators" to "survive the pandemic".

[46] After President Joe Biden said that he planned to select a black woman to appoint to the Supreme Court in January 2022, Wicker told Mississippi radio host Paul Gallo that the nominee would be a "beneficiary" of an affirmative action "quota",[47] drawing a rebuke from the White House.

[48] Wicker was one of 18 Republican senators to vote for the $1.7 trillion omnibus bill that President Donald Trump heavily criticized.

[51] As of December 2017, Wicker ranks 14th of 98 in the Bipartisan Index compiled by The Lugar Center, which reflects a low level of partisanship.

[52] Wicker identifies as a fiscal conservative, but has voted to increase federal spending for agriculture, infrastructure, and military projects throughout Mississippi.

[56] Wicker supported the 2001 United States invasion of Afghanistan and called the U.S. withdrawal in 2021 "one of the biggest foreign policy catastrophes in my lifetime.” He also said, "we were better off with a Korea-like presence".

[67] In a press release, Wicker wrote: "President Reagan once called the Soviet Union 'the focus of evil in the modern world.'

"[79] In 2017, Wicker was one of 22 senators to sign a letter[80] to President Trump urging him to withdraw the United States from the Paris Agreement.

[81] In November 2023, Wicker initially supported the Foreign Pollution Fee Act co-sponsored by Lindsey Graham and Bill Cassidy.

[85] Wicker's support for pro-gun legislation and gun rights has earned him an A+ rating from the NRA Political Victory Fund (NRA-PVF).

[89] One day after the 2015 San Bernardino attack, Wicker voted against a bill, co-sponsored by a Democrat and a Republican, that would make background checks mandatory when a person buys a gun.

"[90] In 2017, Wicker voted in favor of "a joint resolution of disapproval aimed at former President Obama's executive action requiring the Social Security Administration (SSA) place beneficiaries on the National Instant Criminal Background Check System 'mental defective' list.

[95] He previously served on the Board of Advisors for the Global Panel Foundation [de], a nongovernmental organization that works in crisis areas.
