Sen. Lindsey Graham (R-SC) on Sunday urged Donald Trump Jr. to ignore a subpoena issued by fellow Republican Sen. Richard Burr (R-NC).
Graham told Fox News host Maria Bartiromo that he would advise the president's son not to testify again to the Senate Judiciary Committee.
"If I were Donald Trump Jr.'s lawyer, I would tell him, you don't need to go back into this environment anymore," Graham explained. "You've been there for hours and hours and nothing being alleged here changes the outcome of the Mueller investigation."
"I would call it a day," the senator added.
