Speaker Kevin McCarthy in recent weeks has heard similar advice from both a senior House Republican and an influential conservative lawyer: prioritize the impeachment of President Joe Biden over a member of his Cabinet.

Part of the thinking, according to multiple sources familiar with the internal discussions, is that if House Republicans are going to expend precious resources on the politically tricky task of an impeachment, they might as well go after their highest target as opposed to the attorney general or secretary of homeland security.

And McCarthy – who sources said has also been consulting with former House GOP Speaker Newt Gingrich on the issue – has warmed up to an idea that has long been relegated to the fringes of his conference. This week, he delivered his most explicit threat yet to Biden, saying their investigations into the Biden family’s business deals appear to be rising to the level of an impeachment inquiry.

Speaking to CNN on Tuesday, McCarthy signaled that Republicans have yet to verify the most salacious allegations against Biden, namely that as vice president he engaged in a bribery scheme with a foreign national in order to benefit his son Hunter Biden’s career, an allegation the White House furiously denies. But he said that launching an impeachment inquiry would unleash the full power of the House to turn over critical information, mirroring an argument advanced by House Democrats when they impeached then-President Donald Trump in 2019.

“How do you get to the bottom of the truth? The only way Congress can do that is go to an impeachment inquiry,” McCarthy said Tuesday, stopping short of formally moving to open such a probe.
