Mueller is investigating whether the Trump campaign colluded with Russia in its attempt to interfere in the 2016 presidential election.

Indictments were handed down Monday alleging former campaign chairman Paul Manafort and his deputy, Rick Gates, laundered money and failed to file as foreign agents.

Another campaign aide, George Papadopoulus, also was charged with lying to the FBI about his connection with Russians during the campaign.

Hawley said he doesn’t know enough about the indictments to discuss them in detail.

“I can’t speak to the special counsel’s strategy or what he’s doing exactly,” Hawley said. “I don’t know enough to say.”

But, he said, “These indictments that were handed down, they are going to be proved up in court and if these folks are guilty, they should go to jail.”
