President Donald Trump made use of his campaign rally in Minnesota on Thursday, Oct. 10, to blast House Democrats for launching the probe that he called “insane impeachment witch hunt.”

“Now the Do-Nothing Democrat con artists and scammers are getting desperate. Thirteen months, they’ve got to move fast, because they’re not beating us at the polls and they know it, despite the phony polls,” President Trump told the crowd at the Target Center in Minneapolis.

“They know they can’t win the 2020 election, so they’re pursuing the insane impeachment witch hunt. I’ve been going through it now for more times than I’ve been in office,” President Trump said in his first rally since House Speaker Nancy Pelosi (D-Calif.) announced an impeachment inquiry into him on Sept. 24.

The president told the rally attendees that he is “draining the swamp,” saying, “Corrupt politicians and the radical left got rich bleeding America dry, and they knew my election would finally end their pillaging and looting of our country.”

“From day one, the wretched Washington swamp has been trying to nullify the results of a truly great and democratic election,” President Trump said. “They want to erase your vote like it never existed. They want to erase your voice and they want to erase your future. But they will fail because in America the people rule again.”

The president described the impeachment probe as “the Democrats’ brazen attempt to overthrow our government” in order to bruise him ahead of the 2020 election.

House Democrats have launched the inquiry based on a whistleblower complaint alleging that the president in a phone call on July 25 pressured Ukrainian President Volodymyr Zelenskiy to investigate former Vice President Joe Biden and his son’s business dealings.

President Trump has authorized the White House to release a transcript of the call to prove his phone call was “perfect.”

Zelenskiy on Thursday, Oct. 10, also reiterated there was “no blackmail” in the July phone call with President Trump amid Democrats’ attempts to oust the president on the basis of the conversation.
