President Trump called the Justice Department's Russia investigation "a phony witch hunt" at the Conservative Political Action Conference Saturday, suggesting the probes are "trying to take me out with bullshit."

The big picture: Trump's comments come as Democrats ramp up their probes and the Mueller investigation is reportedly winding down. The investigation has already resulted in 199 criminal charges, 37 indictments or guilty pleas and 4 prison sentences.

Driving the news: Trump dedicated a sizable chunk of his CPAC speech to ongoing tariff negotiations with China, disparaging trade between the 2 countries after announcing this week that the U.S. will not increase tariffs on $200 billion of Chinese goods, as was previously suggested. In the latter stretch of his speech, he announced plans to sign an executive order that will require colleges and universities to "support free speech if they want federal research dollars."

Catch up quick: Trump also gave a mini history lesson about the Great Tariff Debate of 1888, ridiculed the House Intelligence committee's planned investigations into his finances, and scorned claims of his administration's collusion with Russia. He asked for his old friends to call him "Don," and sarcastically endorsed the Green New Deal (again).

"The Green New Deal, I encourage it, I think it's really something they should promote. ... No planes, no energy. When the wind stops blowing, that's the end of your electric. Darling, is the wind blowing today, I'd like to watch television."
