Earlier this week, three former President Donald Trump campaign aides were charged by a special federal counsel investigating the 2016 presidential election and its possible ties to Russia.

Two of those aides — Trump's former campaign chairman Paul Manafort and his assistant Rick Gates — were charged with fraud, conspiracy and money laundering. Both pleaded not guilty, according to the Los Angeles Times.

The third, foreign policy advisor George Papadopoulos, "had already pleaded guilty to lying about his contacts with Russians offering 'dirt' on (Hillary) Clinton — and had been secretly assisting prosecutors for months," according to the Los Angeles Times.

Randall Eliason, a former federal prosecutor and George Washington University law professor, offered insight to the LA Times on the federal investigation led by Robert Mueller.

“The signal (Mueller) sends to every other potential witness is pretty clear,” Eliason said, according to the LA Times. “Be like George, come in and cooperate and cut a deal. If you stonewall us, you’ll end up like Manafort.”

There was no evidence of a connection between Trump himself and Russia. Trump, however, did take to social media to express his thoughts on the matter.

On his Twitter account earlier this week, Trump questioned why so much attention was being paid to possible collusion between himself and Russia and not some other accusations between Clinton and her ties to the same country.

"Never seen such Republican ANGER & UNITY as I have concerning the lack of investigation on Clinton made Fake Dossier (now $12,000,000?), the Uranium to Russia deal, the 33,000 plus deleted Emails, the Comey fix and so much more. Instead they look at phony Trump/Russia, 'collusion,' which doesn't exist," Trump said on Twitter, according to Vox. "The Dems are using this terrible (and bad for our country) Witch Hunt for evil politics, but the R's are now fighting back like never before. There is so much GUILT by Democrats/Clinton, and now the facts are pouring out. DO SOMETHING!"
