“They appear to be succumbing to pressure from the administration,” Schiff said on ABC’s “This Week.” 
“The NSA, in particular, is withholding what are potentially relevant documents to our oversight responsibilities on Ukraine but also withholding documents potentially relevant that the senators might want to see during the trial,” he added, referring to the National Security Agency.
The California congressman made the comments after being questioned about a Politico report that said intelligence officials were pushing House and Senate Intelligence committees to forgo the public portion of an annual briefing on world security threats.
The request was reportedly made in an effort to avoid the prospect of top officials publicly disagreeing with Trump on matters related to Iran, Russia and North Korea. 
“Unfortunately, I think those reports are all too accurate,” Schiff said. “The intelligence community is reluctant to have an open hearing, something that we had done every year prior to the Trump administration, because they’re worried about angering the president.”
The NSA did not immediately respond to a request for comment from The Hill. 
Schiff emerged as a focal figure in the House Democrats’ impeachment inquiry into allegations about Trump’s dealings with Ukraine. Trump is accused of pressuring Ukraine to announce politically beneficial investigations and using nearly $400 million in military aid as a source of leverage in his push for the probes. 
The House in December voted to impeach Trump for abuse of power and obstruction of Congress, making Trump just the third president in U.S. history to face Senate removal.
Schiff said on ABC that the facts surrounding the case aren’t “seriously contested” and argued that the White House’s defense supported his position. 
“The only thing really new about the president’s defense is that they’re now arguing, I think, because they can’t contest the facts, that the president cannot be impeached for abusing the power of his office,” Schiff said.
