Democrats are due to make their case that Trump improperly interfered in Congress' probe of his dealings with Ukraine.

Each side has 24 hours over three days to present their case. After the House prosecutors finish Friday, the president’s lawyers will follow.

The two articles of impeachment revealed Tuesday are: one charge of abuse of power and another of obstruction of Congress.

Chairman of the House judiciary committee Jerrold Nadler said on Sunday it is "possible" the House of Representatives could vote on articles of impeachment soon.

Pushing ahead with articles of impeachment, the House Judiciary Committee convenes Monday to formally receive the investigative findings against President Donald Trump as the White House and its allies launch an aggressive attack on Democrats and the proceedings.

She went on to call Trump a "coward'' on gun policy, "cruel'' on immigration and "in denial'' about climate issues.

"Our democracy is what is at stake," Pelosi said. "The president leaves us no choice but to act.''

When House Judiciary Committee Chairman Jerrold Nadler gavels open Wednesday’s impeachment hearings against the nation’s 45th president, he’ll launch the business of actually writing an indictment against U.S. President Donald Trump.

Chairman Jerrold Nadler, D-N.Y., gaveled open the hearing saying, “’The facts before us are undisputed.”

The State Department released the documents to the group American Oversight in response to a Freedom of Information Act lawsuit.
