WATCH: Republicans dodge questions on Trump Jr. emails

Republicans on Capitol Hill tried to avoid commenting on Russia Wednesday, following the release of Donald Trump Jr.’s emails setting up a 2016 meeting with a Russian lawyer who promised dirt on Hillary Clinton.

While members of the GOP dodged questions about Russian election interference and possible collusion with the Trump campaign, at least one Democrat said Trump Jr. was caught red-handed.

Rep. Don Beyer (D-Va.) pounced on the email chain Trump Jr. tweeted out on Tuesday, telling The Hill’s Molly K. Hooper, “it’s more like [getting] caught red-handed, in flagrante delicto. It’s more than a smoking gun -- you can see the bullet being fired.”

Sen. Claire McCaskill (D-Mo.) -- a former prosecutor -- wouldn’t go quite so in her reaction, cautioning her colleagues to “wait until all the facts are out.”

“It certainly didn’t sound right to me that those three guys were going to a meeting on adoption, as it turns out my gut was correct on that,” she added of the meeting that included then-campaign Chairman Paul Manafort and Trump son-in-law Jared Kushner.  

Asked if Trump Jr.’s emails are a “smoking gun” in the Russian collusion investigation, House Oversight Committee member Jim Jordan (R-Ohio) told The Hill, “it’s going to get looked into.”

“Obviously it's a meeting that I wouldn't have taken; in hindsight I think, Donald Junior said this, he probably shouldn't have taken the meeting,” Jordan told The Hill.

Senate Homeland Security and Government Reform Committee Chairman Ron Johnson (R-Wis.) refused to speculate on the issue of Russian collusion.  

“I’m going to let the other committees, Senate Intelligence Committee, complete their work,,” before coming to a conclusion, he said.
