"The articles of impeachment are constitutionally invalid on their face," the seven-page filing continued. The lawyers contend House Democrats fail to allege any crime or violation of law whatsoever, let alone, high crimes or misdemeanors. The House impeachment managers released their opening trial briefing Saturday evening, and Trump's lawyers will give their response by Monday at noon.

The trial will kick off in earnest Tuesday when House impeachment managers will prosecute the case and Trump's lawyers will offer a robust defense over a period of days.
