The American Center for Law and Justice accuses former President Obama of taking "action to empower the entrenched bureaucracy to subvert our national security" and calls on supporters to sign the petition to "stop the soft coup and the rampant leak of classified information" from the Trump administration.

It was unclear to what "revelation" about the State Department the attorney was referring, but Sekulow's tweet came just hours after the conservative group Judicial Watch posted emails obtained from the State Department showing Clinton Foundation business being conducted on Clinton's private email server, which the group claimed proved "collusion" between the agency and Clinton's family foundation.

Trump and his allies claimed without evidence during the campaign that Clinton was involved in a "pay-to-play" scheme at the State Department, trading diplomatic favors for donations to the Clinton Foundation.
