Washington – On the eve of his expected impeachment in the U.S. House of Representatives, President Donald Trump accused Democrats of pursuing an “illegal, partisan attempted coup” and declaring war on American democracy as they seek to remove him from office for pressing Ukraine to investigate political rival Joe Biden.

Trump’s remarks came in a signed letter addressed to House Speaker Nancy Pelosi, released as House lawmakers set the rules for debate ahead of Wednesday’s planned vote on two articles of impeachment – formal charges – against the Republican president.

At the same time, the Senate’s top Republican, Mitch McConnell, signaled he would not allow the expected upcoming Senate trial on impeachment charges to involve more factfinding about Trump’s conduct. The Republican-led Senate is unlikely to vote to convict the president.

The rambling, six-page letter from Trump to Pelosi on White House letterhead largely restated the president’s objections to the impeachment probe, but did so in accusatory and sometimes spiteful language that attacked Pelosi, congressional Democrats, Biden and institutions such as the FBI.

Pelosi, Trump wrote, “is turning the House of Representatives from a revered legislative body into a Star Chamber of partisan persecution” while “scarcely concealing your hatred of me.”
