 -- White House senior policy adviser Stephen Miller spoke Wednesday about sweeping changes the president hopes to make to dramatically decrease the number of legal immigrants allowed into the country each year. The remarks came shortly after President Trump expressed his support for a GOP-led immigration bill that would overhaul the country's immigration system to accomplish those goals.

Miller claimed the current level of immigration hurts American workers and leads to wage stagnation. On that point, several economists flatly disagree. He also said that recent polling showed “immense” public support for stricter, more limited immigration policies and a switch to a so-called merit-based system. The polling on the issue is in fact complicated and shows a wide range of opinions on the topic.

Here are a few more of Miller's claims and how they stand up to the facts:

Claim: Net migration rates are increasing at a “record pace.”

Claim: "Every year, we issue a million more green cards."

Claim: “The reason why some companies want to bring in more unskilled labor is because they know that it drives down wages.”

Claim: The flow of unskilled workers are “reducing pay for [unskilled labor] positions and reducing [native unskilled workers'] chance of getting those jobs."

Claim: “Ultra-high-skilled workers are in the back of the line to get into the country.”

Claim: "Over 50 percent of our households of legal immigrants today participate in our social welfare system."

Claim: “Public support is so immense on this [legislation], just look at the polling data in many key battleground states across the country.”
