West Virginia's governor, Patrick Morrissey, said 24-year-old staff sergeant Andrew Wolfe, who was also shot in the attack, remains in critical condition.

For more on the president's call for immigration reforms, I'm joined by David Beer.

Thank you for joining us today.

Thanks for having me.

Okay, let's start with some of these social media posts from the president.

He wrote last night in a pair of posts demeaning immigrants and calling the country's

immigration policies stupid.

What's your reaction to that?

Well, first of all, this was a horrific attack.

No one condones it.

This is an individual who should be prosecuted to the fullest extent of the law.

Unfortunately, what the president has taken away from this attack is that all of the 53 million, as he says, immigrants to the United States, legal or illegal, are now seen as suspicious, as people who should be driven out of the United States, even denaturalized.

If you can look at the rhetoric in that post, he can't find a single good thing to say about any of the immigrants from any country in the world.

And that's really what's different.

What I see here is the president has for a long time talked

about the problems with certain types of immigration, with illegal immigration, with refugees

and others. But this was really the broadest attack that I can remember on the immigrant population

overall, both legal and illegal, even the naturalized citizens who have taken the oath to the Constitution of the United States.

Trump's Post had a series of pledged reforms, including but not limited to, a permanent pause on migration from all third world countries.

We heard that a few moments ago.

Remove anyone who is not a net asset to the United States and all federal benefits and subsidies
