Comedian-actor Amy Schumer defended her cousin, New York Sen. Chuck Schumer, after Donald Trump mocked the senator's crying at a press conference Monday following Trump's ban on Muslim refugees.

"I know Chuck Schumer and he cannot act, trust me," Amy wrote in an Instagram post Tuesday. "He can barely smile on cue. He was hurt for those people and all the people facing such unconstitutional injustice."

Trump called the senator "fake tears Schumer" and poked fun at the technical difficulties experienced after Sen. Schumer got emotional with House Minority Leader Nancy Pelosi at a rally against the ban.

"This is what he was thinking about at 6:21 a.m.," Amy Schumer wrote in her post. "A Muslim ban is so unconstitutional and cruel. They are good, hard working people and a refugee from the countries he isn't letting people in from have never committed any acts of terrorism on US soil. Never. We need to fight this now and together."

This is what he was thinking about at 621am. This was his tweet after his first soldier died. Also 8 Yemeni women and 7 children died and trump called the raid "successful" Also I know chuck Schumer and HE CANNOT act trust me. He can barely smile on cue. He can't help but be transparent and genuine. He was hurt for those people and all the people facing such unconstitutional injustice. Trump is about to bombard us with so many awful decisions. His Supreme Court pick will be terrifying and he will try and stop same sex adoption and all our other nightmares. We can't get burnt out or overwhelmed and distracted. We need to stay focused and organized. Tell your friends who say "I'm just not political" that that doesn't cut it anymore. We need people alert and fighting for each other's rights. Tell your sheltered friends to wake up and help. If you live somewhere where youve never even met a Muslim person and it feels like this doesn't really affect you. It does. A Muslim ban is so unconstitutional and cruel. They are good, hard working people and a refugee from the countries he isn't letting people in from have never committed any acts of terrorism on US soil. Never. We need to fight this now and together. Call congress. Call the senate. We need to wake up and rise up together. People need our help.

Schumer has been increasingly political as of late, taking on a central spot in the Women's March inauguration weekend. She's also joined forces with her cousin Sen. Chuck Schumer to advocate for gun control, a move prompted in part by shooting deaths in Louisiana that occurred during a showing of her movie Trainwreck in 2015.
