The late-night comedian noted on "The Late Show" that White House chief of staff Reince Priebus called Trump Jr.'s meeting a "nothing burger," but said the emails have turned it into an "all-you-can-prosecute buffet."

Colbert then started reading the emails out loud, but had a coughing fit.

"I’m sorry, I just got a little cough because of this smoking gun I just found," Colbert said while holding up a prop smoking gun.

Colbert slammed Trump Jr. for responding to Rob Goldstone's email by saying, "If it’s what you say I love it especially later in the summer," adding that he's "not talking about a sparkling rosé with some toasted figs and some soft brie."

Trump Jr. on Tuesday released a chain of emails about setting up a meeting with a Russian lawyer who claimed to have dirt on Clinton, then the Democratic presidential nominee.
