A U.S. congressional panel on Friday gave President Donald Trump one week to say whether his legal counsel intends to introduce evidence and call witnesses in upcoming impeachment proceedings that could lead to formal charges of misconduct within a few weeks, Reuters reported.

The Democratic-led House Judiciary Committee sent a two-page letter to the president setting a deadline of 5 p.m. EDT (2200 GMT) on Dec. 6 for the president’s counsel to specify intended actions under the committee’s impeachment procedures.

The procedures set out rules by which the president can call witnesses, introduce evidence and make presentations.

Panel Democratic Chairman Jerrold Nadler set the same deadline for Republican lawmakers on the committee to notify him about intended witnesses and evidence and scheduled a Dec. 9 meeting to consider the matter.

The Judiciary panel is expected to hold a series of impeachment proceedings, including an initial hearing on Wednesday at which legal experts are due to testify about the constitutional grounds for impeachment.
