The chairman of the House Intelligence Committee claimed Friday that the panel could begin impeachment hearings targeting President Trump as early as next week.

California Democratic Rep. Adam Schiff told CNN there would be a “busy couple weeks” ahead even though the rest of the House will be on a two-week recess, with many holding town halls to hear from their constituents about impeachment and other issues.

“I expect subpoenas,” Schiff said, adding that the process will proceed as “expeditiously as possible.”

If the White House stonewalls Congress, Schiff said, “It will strengthen the case on obstruction.”

The panel announced their intention to remain in DC after Trump called for Schiff to resign and House Speaker Nancy Pelosi accused Attorney General William Barr of having “gone rogue.”

They will focus on a whistleblower’s complaint about Trump’s July phone call with Ukrainian President Volodymyr Zelensky, in which he asked for a “favor” and then urged his counterpart to investigate Joe Biden and his son Hunter.

The president said the call was “perfect” and insisted he did nothing wrong.

Democrats allege that he used the power of his office to pressure Zelensky to probe a political rival, and then tried to cover it up.
