President Donald Trump’s 2020 campaign manager Brad Parscale has accused Democrats of engaging in “a seditious conspiracy” to overthrow the president through their impeachment inquiry, and called for House Speaker Nancy Pelosi to resign for betraying her oath of office.

Parscale on Monday, Oct. 14, posted a video of cable newsers criticizing the House Democrats’ impeachment inquiry against President Trump, including the facts the House has not held a formal vote on the matter.

The footage shows the interviewees slammed the inquiry for changing the rules, not a fair way, breaking precedent, a political exercise, a disgrace, a kangaroo court, a political hit job, and double standard.

In a message accompanying the video, Parscale wrote, “Democrats have crossed over the line of partisan politics and have undertaken a seditious conspiracy to overthrow the people’s president.”

The campaign manager then said that Pelosi is “betraying her oath of office” by trying to impeach President Trump.

“Nancy Pelosi should step down for betraying her oath of office and attempting to overthrow our great Republic,” he wrote.

The Trump campaign is challenging Democrats after recently accusing them of taking on a “coup” with the House’s impeachment inquiry.

President Trump himself has also likened the impeachment inquiry to a “coup” and suggested that Pelosi should be sued for allowing it to happen.

The Trump team is trying to fight Democrats on the impeachment probe they started in September after a so-called whistleblower wrote a complaint alleging the president, during a July phone call with Ukrainian President Volodymyr Zelensky, pressured Ukraine to investigate former Vice President Joe Biden and his son’s business dealings.

Although President Trump authorized the release of the transcript as a way to deny the whistleblower  complaint, and President Zelenskiy also confirmed there was “no blackmail” in his call with President Trump, House Democrats are still acting in a secretive manner to carry out the impeachment inquiry process.
