Proceedings at a Senate confirmation hearing got a little testy when Republican Senator Pat Roberts suggested that his Democratic colleague Sen. Ron Wyden should take a Valium.

On Thursday, Treasury Secretary nominee Steven Mnuchin testified in front of the Senate Finance committee and was heavily criticized for his banking record by several Democratic lawmakers, including Sen. Wyden.

"I've got a Valium pill here that you might want to take before the second round," Sen. Roberts said.

Sen. Sherrod Brown jumped into the mix, saying the suggestion was, "just outrageous."

The spat seemingly cleared up later, when Sen. Roberts and Sen. Brown shook hands.
