However, Graham said he was concerned about others involved in the initial stages of the Russia probe.

"I'm very disappointed no Democrats seem to be worried about the corruption at the Department of Justice and the FBI regarding the Clinton email investigation, early stages of the Russian investigation," Graham said. "I'm worried about that."

He also expressed very little confidence that Mueller would find any evidence of collusion.

"I know that from the Judiciary point of view, we found no evidence of collusion between the Trump campaign and the Russians," Graham said. "I think [Sen.] Richard BurrRichard Mauze BurrHillicon Valley: Ecuador says 'road is clear' for Assange to leave embassy | Panel questioned Bannon on Cambridge Analytica | Trump aide says US knew about arrest of Huawei exec | Judges grill DOJ lawyers on AT&T merger appeal Bannon interviewed with Senate Intelligence panel on Cambridge Analytica: report Cohen plea gives Dems new momentum for Russia probes MORE [R-N.C.] said from the Intel point of view that he's seen no evidence of collusion, but we're waiting on Mueller."

Last Thursday, Trump told Bloomberg News that he considered the investigation "illegal," a statement the president doubled down on Sunday morning.

"The illegal Mueller Witch Hunt continues in search of a crime," Trump tweeted out. "There was never Collusion with Russia, except by the Clinton campaign, so the 17 Angry Democrats are looking at anything they can find."

"ALSO, not allowed under the LAW," he said.
