​President Trump on Wednesday used profanity to lash out at Democrats investigating his call with the leader of Ukraine as part of an impeachment inquiry in the House.

“The Do Nothing Democrats should be focused on building up our Country, not wasting everyone’s time and energy on BULLSHIT, which is what they have been doing ever since I got overwhelmingly elected in 2016, 223-306​,” the president posted on Twitter. “Get a better candidate this time, you’ll need it!​”​

Trump has been railing against Democrats, especially Rep. Adam Schiff, chairman of the House Intelligence Committee, who has become the public face of the impeachment effort.

His committee last week released the whistleblower complaint that revealed Trump’s July 25 phone call with President Volodymyr Zelensky in which Trump asked him to investigate Democratic presidential candidate Joe Biden and his son Hunter.

Trump has suggested Schiff be arrested for treason.
