Top McCarthy aide lands at Harbinger

John Leganski, a top adviser to former Speaker Kevin McCarthy, is joining Harbinger Strategies as a partner.

Leganski worked for McCarthy for more than a decade, rising from an intern during his time at Stanford to serving as the California Republican’s deputy chief of staff. Leganski is a specialist on the inner workings of the House and was one of the top aides to McCarthy during his 15-ballot race for speaker in January 2021. Leganski was also among the small group of House GOP aides that hammered out the Fiscal Responsibility Act with the White House last spring.

Leganski will be joining several former top leadership staffers at Harbinger. Partners at the firm include Steve Stombres, former chief of staff to former House Majority Leader Eric Cantor; Kyle Nevins, who ran the floor for Cantor; Manny Rossman, a former chief of staff to two Senate GOP whips; and Jonathan Slemrod, who worked at the Office of Management and Budget and for Senate GOP leadership.

Harbinger’s clients include Airlines for America, Blackstone, Comcast, General Dynamics and Citigroup.
