While hard-line Republicans have pushed back against progressives like Rep. Alexandria Ocasio-Cortez over their Green New Deal resolution, the New York Democrat has found herself an unlikely new ally: a supporter of President Donald Trump.

In a series of tweets on Friday, Ocasio-Cortez said she saw a man and his teenage son putting up a sign outside of her office that read, “Trump supporters for Ocasio-Cortez.”

The sign left the congresswoman “pretty astonished,” she said in a series of tweets describing her encounter with the two.

When Ocasio-Cortez asked the father how he managed “to support both of us at the same time,” she said he replied: “I’ve been saying for years that climate change is our most important crisis. You’re one of the only ones who’s been willing to be decisive on it.”

“I like you. I can tell that you are genuine and fighting for us. You’re real and you get it,” the representative recalled the man as saying.
