New York Sen. Kirsten Gillibrand, a longtime political ally of Bill and Hillary Clinton, said Thursday the former president should have resigned after his affair with intern Monica Lewinsky was disclosed, according to a report.

Asked if the 42nd president needed to step down nearly 20 years ago, Gillibrand told the New York Times: “Yes, I think that is the appropriate response.”

The comments by Gillibrand, who holds the Senate seat vacated by Hillary, make her the highest-profile elected Democrat to make such a statement about the former president.

She did say, however, that social mores were different in the 1990s than today, when Bill Clinton’s conduct looks particularly bad.

“Things have changed today, and I think under those circumstances there should be a very different reaction,” Gillibrand said.

“And I think in light of this conversation, we should have a very different conversation about President Trump, and a very different conversation about allegations against him.”

A rep for Gillibrand later parsed the senator’s statement and emphasized that Bill Clinton should have been forced to resign under today’s social mores.

Gillibrand first came to the Senate in 2010, taking the seat vacated by then-Sen. Hillary Clinton, who became secretary of state for President Barack Obama.
