President Donald Trump defended his executive actions on immigration on Twitter Monday morning and mocked New York Sen. Chuck Schumer for crying at a press conference Sunday.

Reacting to Trump’s executive actions pausing immigration from certain countries, Schumer began to cry while quoting the poem on the Statue of Liberty, “The New Colossus.”

“Give me your tired, your poor, your huddled masses yearning to breathe free…” Schumer said as his voice started to crack. “I won’t read the rest.”

Trump tweeted Monday, “Only 109 people out of 325,000 were detained and held for questioning.”

Trump continued, “Big problems at airports were caused by Delta computer outage, protesters and the tears of Senator Schumer.”

The president wrote, “There is nothing nice about searching for terrorists before they can enter our country. This was a big part of my campaign. Study the world!”

“If the ban were announced” before its enactment, he concluded, “the “bad” would rush into our country during that week. A lot of bad “dudes” out there!”

Trump again mocked Schumer’s tears Monday morning.

“I noticed Chuck Schumer yesterday with fake tears,” Trump said at a meeting of small business leaders. “I’m going to ask him who is his acting coach, because I know him very well. I don’t see him as a cryer. If he is, he’s a different man. There’s about a 5 percent chance that it was real, but I think they were fake tears.”
