Schiff said that Michael Atkinson, the intelligence community inspector general, will appear before the committee in a closed session on Oct. 4 for a briefing. The session comes after Atkinson appeared behind closed doors on Capitol Hill earlier this week.

The Democratic chairman said that a whistleblower complaint against Trump released this week offered “credible and alarming set of allegations that the President of the United States sought to pressure Ukraine to investigate a political rival while also withholding needed military assistance from that country.”

Schiff said he will update members and work with the chairmen of the House Foreign Affairs Committee as well as the Oversight and Reform Committee over the course of the two-week recess.

Those panels are engaged in an impeachment inquiry into Trump over his interactions with Ukraine, with Schiff noting that additional “subpoenas and investigatory steps” will continue to be made during the congressional break.

"The [intelligence community inspector general] conducted a preliminary investigation and determined that the whistleblower complaint was credible. This hearing is critical to establish additional details, leads and evidence,” Schiff wrote to fellow lawmakers.

“We have to flesh out all of the facts for the American people. The seriousness of the matter and the danger to our country demands nothing less.”

A declassified copy of the whistleblower complaint released by the Intelligence Committee earlier this week alleges that Trump sought to enlist Ukraine's help in the 2020 election by urging the country to launch a probe against former Vice President Joe Biden Joe BidenFormer Pence aide: White House staffers discussed Trump refusing to leave office Progressive group buys domain name of Trump's No. 1 Supreme Court pick Bloomberg rolls out M ad buy to boost Biden in Florida MORE, the current Democratic presidential front-runner.

Trump has denied wrongdoing, and insisted that his July 25 conversation with Ukrainian President Volodymyr Zelensky — which is at the center of the complaint — was "perfect" and intended merely to get the country to look into his allegations of corruption.

Schiff said the whistleblower complaint “provides us a road map” for lawmakers' probe, adding that the Intelligence Committee is in the process of “identifying additional witnesses” for open and closed-door hearings.
