Sen. Rand Paul (R-KY) blocked a resolution Thursday that called for the public release of Special Counsel Robert Mueller’s report after Sen. Amy Klobuchar (D-MN), a 2020 presidential hopeful, asked for unanimous consent in the Senate for the resolution. The measure passed the House by a 420-0 vote last month.

"We still have not seen the report,” Klobuchar said on the Senate floor. “I have urged the Department of Justice to release the report, and the administration should not delay in producing the report to Congress."

Sen. Paul objected to Klobuchar’s motion, arguing that “we all want transparency,” but he would like the communications of officials in the Obama administration to be released first, including those of former CIA Director John Brennan and Former FBI Director James Comey, in relation to the beginning of the Russia probe.

"We need to know was there malfeasance, was there misuse of power, did President Obama's administration get involved in an election to infiltrate the Trump campaign to trap them?” he said. "What we need to discover and we do not yet know: Was President Obama involved?"

This is the third time Senate Republicans have blocked the resolution to release the Mueller report, which was turned over to the Department of Justice last week.

"We will agree to see the Mueller report as long as the other side will agree to show us the communications that took place in deciding to promote this fake allegation against the president and whether there was misuse of their office," Paul said on the Senate floor Thursday. "We based this investigation on a lie, we should investigate who the liars were."
