On 17 May 1791, he resigned his position in the Commission of National Education to take an appointment (Minister of Police) in the newly created government, the Guard of Laws. From March 1792 he also held the position of Minister of War. During the War in the Defence of the Constitution in 1792, he went on an unsuccessful diplomatic mission to Berlin to request assistance from the Prussian government. On 4 July 1792, a sudden depression made him resign his ministerial positions. A vocal opponent of the Targowica Confederation and likely an author of an anonymous anti-Targowica brochure, he was specifically requested by the Russian government to not be involved in the negotiations; he also refused to join the Targowica Confederation, even after Poniatowski's accession to it.
