Texas Representative Chip Roy says it's time for a complete pause of US immigration to give the system time to catch up with the overwhelming numbers of illegal immigrants who've made the US their new home.

"There are 51 million people in the US today who are foreign-born...16-percent of the population, that's the most in this nation's history," he says.

And Rep. Roy, a Republican, says there's no better time than now, when criminal illegal immigrants are being rounded up and deported, to round up members of terrorist organizations who've come to America such as the Council on American-Islamic Relations (CAIR) and the Muslim Brotherhood.

"Just like Governor Abbott did in Texas, who declared CAIR as a terrorist organization."

Roy says he has a list of things the Trump administration and Congress need to do.

"We should pass legislation to take away the tax-free status of CAIR. We should pass my bill to vet people for Sharia Law, we should pass the PAUSE Act to freeze immigration."

Rep. Roy's PAUSE act, which he introduced in the US House of Representatives, is the Pausing All Admissions Until Security Ensured (PAUSE) Act, which calls for revision in H-1B programs and would end the OPT program.

Roy says we need to look back 100 years or so to 1920, when there were almost as many foreign-born in the US as there are today, which was around the time the US also severely cut back on immigration, a move that served the nation well for decades in the 20th Century, before politicians decided to open the immigration flood gates.

But there are huge differences between then and now:

"Back then they wanted to assimilate, to learn about American ways in American schools, to be taught that the US is a great nation," but most importantly, he says, "there was no social welfare state and there was no threat from Islamism."

And Rep. Roy told Fox News on Saturday he's leaving his seat in Congress to run for attorney general in Texas because he wants to concentrate on his home state, but he's like to see his PAUSE Act passed first.
