Republican Sen. Tim Scott doesn’t want President Trump to pardon his former national security adviser Michael Flynn, who pleaded guilty Friday to lying to the FBI about his conversations with the Russian ambassador.

“We have to have a way to restore confidence of the American people in their elected officials and the leaders of this country,” Scott told CNN’s “State of the Union.”

“One way you do that is by holding those folks who are, A ,lying to the FBI, you hold those folks accountable. And B, you have a process that is clear and transparent,” he continued.

Flynn was charged with one count of “willfully and knowingly” making “false, fictitious and fraudulent statements to the FBI” in regards to the conversations he had with then-Russian Ambassador Sergey Kislyak days before President Trump was inaugurated.

He is the first Trump administration official to be charged as part of special counsel Robert Mueller’s investigation into Russia’s meddling in the 2016 election.

Flynn faces a maximum of five years in prison and a $250,000 fine for the single felony count.

U.S. District Court Judge Rudolph Contreras told Flynn on Friday that prosecutors would request less punishment “if and only if” he provides substantial assistance “in the prosecution of another person.”
