The House Permanent Select Committee on Intelligence is imploding.
On Thursday, its nine Republican members demanded the resignation of the committee's chairman, Adam Schiff, saying they have "no faith" in the Democrat's continued leadership. The House Republican leader, Kevin McCarthy, tweeted out the letter in support.
