The former director of the Central Intelligence Agency suggested on Saturday that special counsel Robert Mueller's investigations will ensnarl President Donald Trump.

John Brennan on Saturday issued a blistering tweet following the indictments of longtime Trump political advisor Roger Stone.

"Your cabal of unprincipled, unethical, dishonest, and sycophantic cronies is being methodically brought to justice," Brennan wrote.

"We all know where this trail leads," he continued.

"If your utter incompetence is not enough to run you out of office, your increasingly obvious political corruption surely will," he added.
