President Trump responded to a sketch from NBC's "Saturday Night Live" that mocked his national emergency declaration at the border, asking how networks can air "hit jobs without retribution" and labeling it "the real Collusion" in a Sunday morning tweet:

"Nothing funny about tired Saturday Night Live on Fake News NBC! Question is, how do the Networks get away with these total Republican hit jobs without retribution? Likewise for many other shows? Very unfair and should be looked into. This is the real Collusion!"

The big picture: Throughout his presidency, Trump has repeatedly attacked late-night shows and comedians — including "SNL" — for their adversarial takes on his administration.
