Schlossberg has drummed up a large following on social media with frequent posts weighing in on national issues

John F Kennedy’s grandson Jack Schlossberg has said he will run for the US House next year, announcing Tuesday that he was seeking a key New York seat set to be vacated by longtime Democrat 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 mother’s cousin, health secretary Robert F Kennedy Jr.
