Pressure is continuing to build on President Biden and his administration as some Senate Democrats are now saying they support a full investigation into his mishandling of the classified documents found at his home and former office disclosed earlier this month.

Manchin and Kaine joined a noticeably small list of Democrats who have spoken out about the Biden document scandal, while most, especially those up for re-election in 2024, have been reluctant to address the situation.

Rep. Katie Porter, D-Calif., speaks to supporters, volunteers and staff at an election night watch party at the Hilton Orange County Hotel in Costa Mesa, California, on Nov. 8, 2022.

Sen. Debbie Stabenow, D-Mich., who announced she would not be running for re-election next year, acknowledged it was a bad look for Biden to be caught having classified information after condemning former President Donald Trump for a similar situation.

Fox News Digital reached out to every Senate Democrat who has yet to make a statement on the Biden documents and whose term ends in 2024, but all except Manchin and Kaine didn't respond.

Sen. Ben Cardin, D-Md., told Politico on Jan. 10, prior to the appointment of a special counsel, that he felt the situation was "being handled properly," but did not respond to Fox's request for comment.
