Conway most recently voiced his displeasure with the appointment of Matt Whitaker as the acting Attorney General.
George Conway, a conservative attorney whose wife is Donald Trump's senior White House counselor, has formed an organization whose goal is to push back against the president.
Charter members of the group, called Checks and Balances, include former Homeland Security Secretary Tom Ridge, former acting Attorney General Stuart Gerson, former Deputy Attorney General Paul McNulty and former Deputy White House Counsel Phillip Brady.
'We believe in the rule of law, the power of truth, the independence of the criminal justice system, the imperative of individual rights and the necessity of civil discourse,' the group says, seeming to spell out a list of what its members see as the president's shortcomings.
'We believe these principles apply regardless of the party or persons in power.'
