House Intelligence Committee Chairman Adam Schiff said on Sunday the findings in special counsel Robert Mueller’s report were more significant than the Watergate scandal that led to the end of Richard Nixon’s presidency.

Schiff, D-Calif., was pressed by “This Week” host Martha Raddatz to answer for his past assertions that there was “ample and abundant” evidence of collusion between President Trump and Russia. She pointed out that Schiff said on the show previously the alleged scandal was “of a size and scope probably beyond Watergate.”
