A watchdog group has filed a new ethics complaint against House Intelligence Committee Chair Devin Nunes (R-Calif.) , alleging he leaked confidential information.

The complaint, filed by the nonpartisan Campaign for Accountability, calls on the Office of Congressional Ethics to investigate whether Nunes or committee staff leaked closed-door testimony of the head of the company that produced the bombshell dossier of Russian information on Donald Trump.

Parts of the confidential testimony apparently were “selectively leaked” to discredit Fusion GPS and to “retaliate against Fusion for its role in investigating” Trump and his campaign’s ties to Russia, according to the complaint. It alleges the leak further aimed to “deter the firm from engaging in any continued investigation.”
