WASHINGTON – ​President Trump said First Lady Melania Trump witnessed a “very sad situation” during her two visits to the Mexican border but also “saw the danger.”

“She came home and told me a couple of things. She said it’s a very sad situation, very, very sad,” Trump recounted to Fox News’ Maria Bartiromo ​on “Sunday Morning Futures.” “She was really impressed with border patrol, how ​professional they were. She came and said that, and she was really saddened by the plight of people.”

The president described his wife as having a “very big heart.”

“But she was so strong on how professional the border patrol, the agents, the law enforcement is along the border,” he said​ in the interview that aired Sunday​. “She couldn’t believe it.”

“And she saw the danger. She saw the – you look ​at ​it. It just looks like danger. In the meantime we have to have strong border protection,” he added.

Trump ​pushed ​back on Democrats ​and the thousands of people who rallied across the country on Saturday to protest his immigration policy that has led to thousands of children being separated from their parents and to call for an end to Immigration and Customs Enforcement.

​He relished how the Democrats’ ​position would help him politically.

“You get rid of ICE you’re going to have a country that you’re going to be afraid to walk out of your house,” Trump said. “I love that issue if they’re going to actually do that.”

​T​he president answered in the negative when asked if images of children being separated from their parents at the border were going to hurt Republicans in the midterm elections.

“No,” Trump said. “First of all I signed an executive order last week saying I don’t want families broken up. Nobody else did that.”

He also suggested the Democrats’ leftward swing – ​namely ​with ​28-year-old Democratic-Socialist Alexandria Ocasio-Cortez​’s win over Rep. Joe Crowley ​in last week’s Democratic primary – would end up hurting the party.

“Between Maxine Waters and Nancy Pelosi and getting rid of ICE and having open borders … all it’s going to do is lead to massive, massive crime. That’s going to be their​ platform, open borders, which equals crime,” Trump said, naming two liberal and vocal members of the Democratic ​P​arty. “I think they’ll never win another election.”

“So I’m actually quite happy about it,” the president said.
