President Donald Trump s former longtime pal and onetime White House communications director, Anthony Scaramucci , was spotted Saturday at a Southampton charity event featuring former Vice President Joe Biden .

Scaramucci insisted that hes still a registered Republican and hasnt switched his support to the Democratic presidential candidate. But he also said he will be working to find a nominee to challenge Donald Trump because hes lost his mind. And weve got to ... get somebody in there before we lose the election in 2020.

Scaramucci appealed the previous day in an MSNBC interview to Republican leadership to convince Trump to step down before he embarrasses himself and let Vice President Mike Pence take over. He accused Trump of melting down like a nuclear reactor and said hes in early-stage full-blown fascism.

Biden spoke at the Blue Dream Gala , a charity event hosted by the Greek Orthodox Church of the Hamptons .

I know Im crashing your party here, quipped Biden. He honored the Greek community and Greek Orthodox leaders for their support after the death of his son Beau, who died in 2015 of brain cancer at the age of 46.

He then segued from religion to politics: I think were in a battle for the soul of our nation. I think were in a battle for who we are, the battle that defines our values, our basic rights we all share ... that the birthright of every single child of God is to be treated with dignity and committed to one another.

He added: Now more than ever we need the United States to stand for the values that unite us, and to lead the world. We cant forget that democracy is the root of our society, the wellspring of our power.

The gala raises funds for one main charity each year. The charity chosen in 2016 was the Beau Biden Foundation , founded in honor of Bidens son.
