Could 2018 be the year of investigations?

It's hard to believe, but it hasn't even been a year since Donald Trump took the oath of office to become President of the United States.

But 11 months, ten days, and more than 2,400 tweets later, here we are.

"Well here we go. Put your seat belt on -- it's been an interesting first year," said Rudy DeLeon with The Center for American Progress, looking back on Trump's presidency.

But it's also time to look ahead to 2018 -- a year some believe could defined by investigations.

Special counsel Robert Mueller's is still going strong, already resulting in charges against three former Trump campaign officials and a guilty plea by former National Security Agency Director Michael Flynn.

Democrats on Capitol Hill are hoping the investigation continues in as thorough a manner as possible.

"I am standing with Mueller. I am so comfortable standing with him, I signed on to a letter of support for him," said Rep. Joyce Beatty, D-Ohio, in a recent interview.

Republicans are calling for many more answers as well.

Sen. Rand Paul, R-Ky., in a tweet called for an investigation into Obama administration officials he says may have colluded to prevent a Trump election.

Other GOP lawmakers want to know whether Hillary Clinton got special treatment by the FBI during the investigation into her emails.

"My constituents say what is going on in the investigation into crimes of the previous administration," said Rep. Andy Biggs, R-Ariz., during a Capitol Hill hearing in July.
