"Please provide the Committee with the notice of whether your counsel intends to participate, specifying which of the privileges your counsel seeks to exercise, no later than 5.00 pm on 6 December 2019", the committee’s chairman Jerrold Nadler wrote to Trump.
In a separate letter to Congressman Doug Collins, Nadler asked if the top Republican on the committee would like to issue any subpoenas or interrogatories related to the matter. Collins was also given a 6 December deadline.
"I am prepared to schedule a meeting of the Committee on Monday, 9 December 2019 to consider any such referrals", Nadler said in the latter.
The panel earlier said that it would hold its first impeachment hearing on 4 December to discuss constitutional grounds for presidential impeachment and analyze the evidence gathered thus far - mainly through depositions of witnesses in the House Committee on Intelligence.
The president has hitherto refused to cooperate with the probe initiated by House Democrats who seek to prove that he abused his powers by pressuring Ukraine into investigating his political rivals – former Vice President Joe Biden and his son Biden. Trump has repeatedly said that he did not engage in a quid pro quo and characterized the impeachment bid as another political 'witch hunt' by Democrats to reverse the results of the 2016 presidential election.
