At a closed-door briefing Wednesday, National Intelligence Director Avril Haines declined to show the Senate Intelligence Committee copies of classified documents discovered at Donald Trump's Mar-a-Lago resort and Joe Biden's office and Delaware home. Committee Chairman Mark Warner and Vice Chairman Marco Rubio expressed their disappointment, while Sen. Tom Cotton threatened to block presidential nominees or funding for some federal agencies until the Biden administration shows the documents. The Biden administration has yet to comment on the issue, and it is unclear when the documents will be made available to the committee.
