During a joint press conference with Norwegian Prime Minister Erna Solberg, President Donald Trump refused to answer questions on whether or not he'd grant an interview to special counsel Robert Mueller — and instead reiterated that he engaged in "absolutely no collusion" with Russians.

"You ready to try out your 'no collusion with Russia' line with Team Mueller under oath, Don?" Observer's John Schindler tweeted.

"That's not how any of this works," another user responded.
