The New York Times reports:
House Democrats signaled that they would unveil articles of impeachment on Tuesday morning that charge President Trump with abuse of power and obstruction of Congress for conduct they called a “clear and present danger” to the 2020 election and national security. The House Judiciary Committee was expected to work through the night on Monday readying the charges, according to multiple senior officials and lawmakers.
They cautioned that plans were not final, but several officials said they were now focused on two charges: that Mr. Trump violated his oath of office by putting his political concerns over the national interest and that he stonewalled congressional attempts to investigate. The officials spoke on the condition of anonymity in order to discuss the decision before it was ready.
