'A Teachable Moment': Veterans Talk to Teens Who Defaced American Flag

Ann Coulter said she hopes Trump returns to "campaign mode" and follows through on his promises on illegal immigration and border security.

"He gets instant feedback from the crowd and that's when he says really popular things that get Republicans elected and could possibly defend against a blue wave," Coulter said on "The Next Revolution."

"But then he gets back to Washington and he's not doing anything."

She pointed to the caravan of hundreds of Central American migrants at the San Diego border crossing who are seeking asylum in the U.S.

The author and syndicated columnist said those migrants are "100 percent" still coming to the border, despite Trump previously claiming they were stopped by Mexican authorities. Coulter called on the president to pressure Congress on the issue. 

"He's not doing anything about the caravan. ... Pass a law saying you don't get to step in and say, 'I'm claiming asylum,' and then get a bus and a boxed lunch into America," Coulter said.

She called it a "political attack" on the U.S. by groups who do not believe nations should have borders, explaining that the migrants are separating into smaller groups to enter at different access points.

"We did not elect Jeb Bush," Coulter said, warning of a possible "huge blue wave" in November's midterm elections if Trump doesn't turn his focus from Syria, North Korea and tax cuts back to immigration and trade.

"That's the only way to stop a blue wave."

Coulter took issue with a comment Saturday night by Trump in which he expressed support for "guest workers" to work on U.S. farms.

"The unemployment picture is so good, it's so strong, that we have to let people come in," Trump said at a rally in Michigan.

"They're going to be guest workers. They're going to come in, they're going to work on your farms ... but then they have to go out."

Coulter said she was puzzled by the comment about the H2B visa system, noting the "dead silence" from the crowd during the portion of the speech.
