Story highlights The administration has not provided any information about President Donald Trump's allegations

Republican leaders in the Capitol have largely distanced themselves from the accusations

Washington (CNN) Sen. Lindsey Graham said Wednesday he is ready to subpoena the intelligence agencies for evidence that would prove President Donald Trump's claims that he was wiretapped last year by then-President Barack Obama.

Asked by CNN if he would subpoena for any evidence, the South Carolina Republican said, "Yes."

"All I can say is that the country needs an answer to this. The current President has accused the former President of basically wiretapping his campaign," Graham said, one day after he joined Trump for a one-on-one lunch at the White House.

Graham and Sen. Sheldon Whitehouse, a Rhode Island Democrat, sent a letter to FBI Director James Comey and the acting deputy attorney general Wednesday, requesting any information regarding Trump's claims.

"We request that the Department of Justice provide us copies of any warrant applications and court orders — redacted as necessary to protect intelligence sources and methods that may be compromised by disclosure, and to protect any ongoing investigations — related to wiretaps of President Trump, the Trump Campaign, or Trump Tower," Graham and Whitehouse wrote.
