The House GOP’s newly announced impeachment inquiry into President Biden is scaring the bejesus out of Sen. John Fetterman (D-Penn.)

Not really.

“Oh my God, really? Oh my gosh, it’s devastating,” Fetterman said mockingly with a few chuckles Tuesday when asked about the news. “Oooh, don’t do it, please don’t do it.”

Wearing a button-down shirt and his signature big shorts in a congressional corridor, the Pennsylvania senator made clear he doesn’t take the probe seriously.

Fetterman, who was impaired with a speech impediment and auditory processing issue after a stroke in May 2022, appeared strikingly articulate in his response.

House Speaker Kevin McCarthy (R-Calif.) announced Tuesday that he is directing House committees to initiate an impeachment inquiry into President Biden.

“House Republicans have uncovered serious and credible allegations into President Biden’s conduct” in foriegn-business dealings involving his family, including son Hunter, McCarthy said. “Taken together, these allegations paint a picture of a culture of corruption.

“Through our investigations, we have found that President Biden did lie to the American people about his own knowledge of his family’s foreign business dealings,” he added.

McCarthy’s announcement seemingly chafes with a prior public commitment he made to hold a floor vote to commence any impeachment inquiry.

He told Breitbart earlier this month, “If we move forward with an impeachment inquiry, it would occur through a vote on the floor of the People’s House and not through a declaration by one person.”

The speaker also previously criticized his precedessor Nancy Pelosi for starting an impeachment probe against then-President Trump without a floor vote.

In the time since, a handful of House Republicans came out in opposition to an impeachment inquiry against Biden.

Both Biden and the White House have vehemently ripped GOP accusations of wrongdoing by the president.

“House Republicans have been investigating the president for nine months, and they’ve turned up no evidence of wrongdoing,” White House spokesman Ian Says said.

“[McCarthy’s] own GOP members have said so. He vowed to hold a vote to open impeachment, now he flip-flopped because he doesn’t have support extreme politics at its worst,” the rep said.

With the impeachment inquiry, congressional Republicans find themselves with added firepower to subpoena witnesses and documents in their investigation.

McCarthy himself has publicly sought Biden’s bank records.

He has faced enormous pressure from his right flank to begin an inquiry as he juggles a budget battle –with just 11 days in the congressional calendar until a government shutdown at the beginning of October.

The House gaveled into session Tuesday after a six-week recess.
