Democrats are expected to announce on Tuesday two articles of impeachment against Donald Trump, US media reported Monday evening, after laying out their case at a hearing against a president they branded a "clear and present danger" to national security.

The articles will focus on abuse of power and obstruction of Congress, The Washington Post said, citing three official familiar with the matter.

It added that the full House of Representatives would vote on the articles next week, ahead of a trial in the Senate.

CNN said a third article on obstruction of justice was still being debated, and the network's sources cautioned that plans were still being finalized.

Democrats are moving ahead with the impeachment of President Donald Trump following another day of testimony on Monday.

"House Democrats plan to unveil at least two articles of impeachment Tuesday, charging President Donald Trump with abuse of power and obstruction of Congress, according to multiple lawmakers and aides. The Judiciary Committee plans to vote on the articles on Thursday, setting up a vote on the House floor next week to make Trump the third president in history to be impeached," Politico reported Monday evening.

"Democratic leaders plan to formally announce the articles at a press conference Tuesday morning. Judiciary Committee Democrats intend to meet ahead of the announcement and review the articles," Politico reported. "The decision to move forward with specific impeachment charges is the most significant move yet for the year-old Democratic House majority, a legacy-defining moment for Speaker Nancy Pelosi that sets up a Senate trial for Trump in early 2020."
