President Trump, reiterating his firm belief that Special Counsel Robert Mueller's investigation had been a political and unsuccessful witch hunt, tweeted out the New York Post's front page and its bold, declarative headline: "TRUMP CLEAN."

The page showed Trump smiling alongside the phrases, "No crimes committed," and "Dem hoax destroyed."

The tweet was something of a victory lap for Trump, after Mueller's report said there wasn't enough evidence to charge him with either conspiracy or obstruction of justice.

Despite what Trump's tweets may have implied, the battle was far from over, however, as congressional Democrats continued to push their own follow-up investigation. House Judiciary Committee chairman Jerrold Nadler, D-N.Y., subpoenaed the unredacted Mueller report and requested that Mueller testify before Congress.

Rep. Eric Swalwell, D-Calif., who also serves on the Judiciary Committee, spoke of concerns about Russian election meddling and collusion. He said that even though Mueller's report didn't show collusion "beyond a reasonable doubt," it contained enough suspicious information to raise red flags.

"There was certainly evidence of collusion, not evidence that met the beyond a reasonable doubt standard," he said.

Sen. Elizabeth Warren, D-Mass., called for impeachment proceedings in the aftermath of the Mueller report's release, and pushed back on concerns that the issue might hurt Democrats' 2020 prospects.

“I know people say this is politically charged and we shouldn’t go there, and that there is an election coming up, but there are some things that are bigger than politics,” she said.

Reps. Alexandria Ocasio-Cortez, D-N.Y., and Rashida Tlaib, D-Mich., also pushed a resolution calling on the House Judiciary Committee to investigate whether Trump committed impeachable offenses.

Those reactions aside, though, Trump was exuberant, according to his adviser Dan Scavino.

While the president touted the Post's front page, it also had its share of critics who felt it was an astounding example of overreach.
