Sen. Jeff Flake was met with a smattering of boos from the crowd at Saturday's Global Citizen Festival in New York City.

Flake (R-Ariz.) appeared on the stage with Democratic Sen. Chris Coons (DE) and stated the two lawmakers were at the event to "support bipartisan leadership on foreign aid."

Coons implored the crowd to reach out to lawmakers because "there are people’s voices we need to hear from around the world and here in our own country."

“So feel free to join me in an elevator any time,” Flake added.

The quick remark didn't sit well with the audience, as Flake was met with boos and jeers from the crowd before him.

"This isn't going too well for Jeff Flake," Rachel Campos-Duffy said Sunday on Fox & Friends.

Flake was referencing the confrontation he had in a Capitol Hill elevator with protesters on Friday.

The two women explained to the lawmaker that they were victims of sexual assaults and began shouting at him over his expected "yes" vote for Brett Kavanaugh.

Flake thereafter called for an FBI investigation into the sexual misconduct allegations against the Supreme Court nominee from Christine Blasey Ford.

"The point about Jeff Flake here is he's retiring, so we don't know what his next chapter in life is," Griff Jenkins added. "Here, he's looking for acceptance into what may be his next act."

According to its website, Global Citizen "is a movement of engaged citizens who are using their collective voice to end extreme poverty by 2030."
