Sen. John Thune (R-SD) said he does not believe a special prosecutor will be appointed to look into Russia's interference in the 2016 election.

Democrats and some Republicans have called for an independent investigation into possible collusion between the Trump campaign and Russia. 

Sen. John McCain (R-AZ) said a "select committee" should be set up following the firing of FBI Director James Comey by President Trump. 

Thune was asked by Bill Hemmer whether a special prosecutor is needed.

"That's not gonna happen," said Thune, noting there are already multiple congressional investigations underway, along with the FBI probe. 

He said those investigations are "objective" and will "get to the bottom" of the matter. 

Thune, however, said he does have questions about the "timing" on the firing of Comey. 

"The timing was right on the heels of an announcement that there was gonna be a grand jury seated to ask questions about the investigation into Russia. ... The timing was a little odd in my view," said Thune, adding he will wait for an explanation from the White House and Justice Department for why the firing happened at this time.

Thune said Comey had gone "outside his lanes" over the past year, becoming too public instead of staying behind the scenes and that there has been "bipartisan support" for Comey to be replaced.
