The Justice Department’s first hearing on “Constitutional grounds for impeachment of the President” is expected to open fire for a turbulent month in the House of Representatives.

The jury is scheduled to hold several public hearings, then weigh the terms of impeachment, which in turn approves the holding of a House of Commons vote before Christmas, which would likely cause him to. Trump became the third President impeached in American history.

The President’s advisers are allowed to participate in impeachment hearings by the Judiciary Committee, unlike those of the House Intelligence Committee last month.
