“There is no precedent for this: to take a memorandum about the FISA application process, write a memo, vote it out on party lines — and then clearly there was some coordination with the White House,” said Michael Allen, a former staff director for the committee under then-Chairman Mike Rogers, a Michigan Republican.

“If this leads to widespread condemnation (of the committee) and the whole exercise becomes discredited, people will not want to go there again,” Allen said. “But if this comes off well for the committee, this will increase the risks that people will use the intelligence committee as a political platform.”
