State senator Samuel Douglass, 26, and wife, Brianna, both made comments in Young Republicans Telegram group

A Vermont state lawmaker has resigned over racist and antisemitic chat messages that circulated within the Young Republican political group, another substantial consequence in a scandal that on Friday saw the New York state Young Republicans’ charter revoked.

State senator Samuel Douglass, the only elected official known to have taken part in the leaked group chat exposed by Politico, resigned Friday over his participation.

In a statement posted online, the 26-year-old Douglass said he was “deeply sorry for the offense” caused by his comments. He added that his decision to step down, effective Monday, “will upset many, and delight others, but in this political climate I must keep my family safe”.
