House Republicans are planning to subpoena former FBI Director James Comey and Obama administration Attorney General Loretta Lynch - and Comey has already responded.

"Truth is best served by transparency"

The former FBI director who has become a vehement foe of the president responded via a tweet on his social media account.

"House Republicans can ask me anything they want but I want the American people to watch, so let’s have a public hearing," Comey tweeted. "Truth is best served by transparency."

"Let me know when is convenient," he challenged.

The tweet came after House Judiciary Committee Chair Bob Goodlatte (R-Va.) revealed that one of the last acts of the committee would be to subpoena Lynch and Comey to testify before Congress after Thanksgiving.

Comey's attorney David Kelley also responded to the report to CNN.

"We have not heard from them since October 1 when we advised the Committees (Judiciary and Oversight and Reform) that, while we respectfully declined their invitation for a closed door interview, we would welcome the opportunity to testify in a public hearing," Kelley said.

Democrats are angry about it

Democratic Rep. Jerry Nadler (N.Y.) angrily denounced the report of the subpoenas in a statement Friday.

"It is unfortunate that the outgoing Majority is resorting to these tactics," Nadler said. "Months ago, Director Comey and Attorney General Lynch both indicated their willingness to answer the Chairman's questions voluntarily. My understanding is that the Republicans have had no contact with either the Director or the Attorney General since."

Nadler is widely considered to be the next chairman of the House Judiciary Committee, after the Democrats take control of the House of Representatives.

"These subpoenas are coming out of the blue," Nadler continued, "with very little time left on the calendar, and after the American people have resoundingly rejected the GOP's approach to oversight — if, indeed, 'oversight' is the word we should use for running interference for President Trump."

"Witnesses have an obligation to comply with committee subpoenas, but the committee has an obligation to issue those subpoenas with care," he concluded.

Democrats plan to use their newly acquired subpoena powers in the House to begin their own investigations into President Donald Trump and his administration.
