John F. Kennedy's grandson Jack Schlossberg is running for the U.S. House next year, announcing Tuesday that he's seeking a key New York seat set to be vacated by longtime Democratic Rep. Jerry Nadler.

This district should have a representative who can harness the creativity, energy and drive of this district and translate that into political power in Washington, Schlossberg said in a campaign video posted on social media late Tuesday.

In an email to supporters, Schlossberg, a Democrat, said that his campaign will officially launch on Wednesday.

Schlossberg has drummed up a large following on social media with frequent posts weighing in on national issues, including taking aim at his cousin, Health Secretary Robert F. Kennedy Jr.
