Scott Pruitt, ex-head of EPA, to run for Senate seat in Oklahoma

Scott Pruitt, who resigned as head of the Environmental Protection Agency amid ethics scandals during the Trump administration, is running for an open U.S. Senate seat in Oklahoma.

The former state attorney general filed his campaign paperwork on Friday. He now joins a crowded race to replace 87-year-old Republican Sen. James Inhofe, who is retiring after the midterm elections.

Pruitt will attempt to return to Washington, where he worked as the EPA's former President Donald Trump's EPA chief.

During his stormy tenure as the head of the agency, Pruitt was Trump's point man for the administration's efforts to roll back environmental regulations, many of which had been put in place by the Obama administration.

Pruitt's efforts were largely overshadowed by a barrage of media reports that detailled questionable spending and management decisions, including frequent first class travel and expensive trips paid for by the government, as well as reports of big pay raises for top aides without White House approval, and reports that Pruitt sidelined staffers who questioned him.

During congressional testimony, it was revealed that Pruitt routinely tasked EPA aides with carrying out personal tasks for him and other members of his family. He was accused of misusing government funds, including spending $43,000 on a soundproof booth for his EPA office, $1,500 on a set of 12 fountain pens and $5,700 on biometric locks for his office doors.

Pruitt will face off against a number of Republicans seeking the Senate seat in Oklahoma. Inhofe's former chief of staff, Luke Holland, has been endorsed by his old boss.

Friday was the last day for candidates to file paperwork to enter the race.

In Oklahoma, Trump defeated President Joe Biden with 65 percent of the vote in 2020, while Inhofe won the election with over 62 percent of the vote the same year.

Sources told NBC News last month that Pruitt had been seeking Trump's endorsement while mulling a run for the seat.

Trump has not made an endorsement in the race.

Taylor Budowich, a Trump spokesman, said last month that every candidate running in America is seeking President Trump's endorsement.
