Washington (CNN)A Utah Republican senator on Sunday said he was ”certain” the next Congress will look into President Donald Trump’s ties to Saudi Arabia after the President signaled he would not punish the Saudi crown prince over the murder of Washington Post journalist Jamal Khashoggi.

”Look, I don’t know why he’s siding with the Saudis, but I think there are things we can do to change our relationship with the Saudis notwithstanding whatever his personal motivations might be,” Sen. Mike Lee said on NBC’s ”Meet the Press.” ”I’m also certain in the next Congress people will look into that.”
