A top lawyer for the Treasury Department resigned Monday after the Justice Department announced the creation of a nearly $1.8 billion “anti-weaponization” fund to compensate what it described as lawfare victims of the Biden administration.

Brian Morrissey’s departure came hours after the fund was announced as part of an agreement to settle a lawsuit brought by President Donald Trump against the Internal Revenue Service over the leaking of his confidential tax records. The IRS is overseen by the Treasury.
