Basking in an energetic Iowa crowd Wednesday night, President Donald Trump slammed his most frequent targets and promised lofty policy changes in the near future.

The president looked comfortable riffing and embellishing in front of the Cedar Rapids audience for more than an hour. Trump came to Iowa from a Washington in which his administration has appeared to struggle under the weight of constant controversy and he's seemed frustrated by the pace of policy changes.

In the campaign-style rally, Trump hit out at some of his favorite targets — "fake news" media outlets, "obstructionist" Democratic lawmakers and the Clinton family. He also touted what he deemed his accomplishments so far and defended his inability to quickly follow through on some of his key campaign promises.

Aside from policy hurdles, the president faces a reported investigation into whether he attempted to impede the probe into Russian interference in the 2016 election, following reports that he asked then-FBI Director James Comey to go easy on an ally. Trump contended that the Russia probe — which he again called a "witch hunt" — will not slow his agenda.

"They have phony witch hunts going against me, they have everything ... and all we do is win, win win," Trump said.

The rally featured the staples of Trump's raucous campaign — "lock her up" chants about his 2016 rival Hillary Clinton, calls to "build the wall" on the U.S. border with Mexico and protesters getting escorted out of the venue.
