‘Meet the Press’ moderator speaks with Homeland Security Secretary Kristi Noem, Sen. Mark Kelly and Gov. Tim Walz

(NBC, KYMA) - "Meet the Press" moderator Kristen Welker spoke with Homeland Security Secretary Kristi Noem, Sen. Mark Kelly (D-Ariz.) and Gov. Tim Walz (D-Minn.) Sunday.

During her interview with Secretary Noem, Welker asked the secretary if she knows what the motive was behind the shooting of two National Guard members, and if she believes the suspect, identified as 29-year-old Rahmanullah Lakanwal, an Afghan national, acted alone, and Noem said:

"We're still going through all of that information, and I'll let the FBI and DOJ reveal new information. But I will say we believe he was radicalized since he's been here in this country. We do believe it was through connections in his home community and state, and we're going to continue to talk to those who interacted with him, who were his family members, who talk to them. So far, we've had some participation. But anyone who has information on this needs to know that we will be coming after you, and we will bring you to justice. We absolutely will persecute you because we do know that we will never allow this to continue to happen in our country, allow individuals who came to our country, that were unvetted by Joe Biden, allowed to run free and loose. We are going to bring them to justice and make sure that they're returned out of this country if they aren't here for the purposes of being an American."

Welker then asked why the Trump Administration granted Lakanwal asylum earlier this year, and if they knew then he was moving towards radicalization, and Noem said:

"When this abandonment of Afghanistan happened, the Biden administration put people on airplanes, brought them to the United States without vetting them. They brought them into our country and then said they would vet them afterwards. And then at that time, to do a good job of vetting people, you need to have cooperation of that government that is from their country. You have to have a stable government that will give you information, contacts, background information, and biometrics that you may need to identify that individual, their dates of service. All of that vetting information was collected by Joe Biden's administration, that was used in the process. So President Trump thankfully has completely changed that. We are now using all social media content. We're going after what they have been doing with their contacts, their biometric data information we are collecting. Now when we vet individuals under this administration, we know who they are, why they are here in going through that. Unfortunately, this individual, that entire process happened under Joe Biden's watch."

When asked if the Trump Administration will deport people with pending asylum claims, Noem said:

"We will if they should be, absolutely. Yes. We are going to go through every single person that has a pending asylum claim, has an asylum claim here in this country. You know, one of the requirements of asylum is that you have to come in every single year for a check-up and interview process, and a re-vetting. And that is something that we're going to expedite, and happen immediately with anyone who does have that asylum claim today and ensure that they deserve to still be in this country, that they still have the purposes for which they claimed that asylum in place. And that they're not here being radicalized and perpetuating dangerous criminal activity against our Americans."

During Sunday's edition of "Meet the Press," Welker spoke with Sen. Kelly to get his response to President Donald Trump's threat to pause immigration from "third-world countries" following the shooting of two National Guard members.

"Let me start by saying what happened to the two Guardsmen, Andrew Wolfe, Sarah Beckstrom, horrific. And it shouldn't happen. And I'm praying for him and for her family. It was a horrible, horrible thing. And there needs to be an investigation and accountability. But when I heard the Secretary say that they're going to pause immigration from third-world countries, I mean, I take that as a message that they don't want brown people coming to the United States. And I find that disturbing. We are a country that has always welcomed individuals that are struggling, that are fleeing famine and violence. And it would be a fundamental change to the fabric of our nation to change that."

Welker then asked if the senator believes former President Joe Biden's actions bear any responsibility in light of the shooting, and Kelly said:

"This administration, they're going to blame Joe Biden on everything. I mean, it is almost getting comical, you know, at this point. It sounds like there was some vetting done in the last administration. It sounds like they did not do enough vetting before they gave him his asylum claim. She talked about changing the vetting process. I think that's a good idea. I mean, when you see an issue and a process that isn't quite working especially after we go through an investigation on this individual, if there are things that need to be changed, we should change them. I used to have a boss, a commanding officer in the Navy, that would tell me that, 'If you're not changing things, they're getting worse. Process improvement is important.'"

During the interview, Welker asked Kelly if he plans on cooperating with the Pentagon's investigation regarding the allegations of misconduct after he and several Democratic lawmakers posted a video calling on U.S. service members to disobey illegal orders.

"Just like saying that we should be hanged, executed, that's about intimidating. Sending the FBI after us, that's further intimidation. I'll follow the law, but I'm not going to be intimidated. I'm not going to be bullied, especially by Donald Trump and Pete Hegseth," Kelly answered.

Later in Sunday's edition of "Meet the Press," Welker spoke with Gov. Walz regarding his post on social media calling on President Trump to release his MRI results after the president, in a social media post, used a slur against Walz as well as made claims about Somali refugees in Minnesota.

"We have a guy on Thanksgiving, where we spent time with our families, we ate, we played Yahtzee, we cheered for football, or whatever. This guy is appropriately in a room, ranting about everything else. This is not normal behavior. It is not healthy. And presidents, throughout time, have released a couple things. They've released their tax returns, not Donald Trump. And they've released their medical records, not Donald Trump. And look, the MRI is one thing. But I think what's most concerning about this is, as your viewers out there are listening, has anyone in the history of the world ever have an MRI assigned to them and have no idea what it was for, as he says? So look, it's clear the president's fading, physically. I think the mental capacity, again, ranting, you know, crazily at midnight on Thanksgiving about everything else, there are reasons for us to be concerned. This is a guy that randomly says the airspace over Venezuela is closed. He's ruminating on if you could win a nuclear war. Look. This is a serious position. It's the most powerful position in the world. And we have someone, at midnight, throwing around slurs that demonize our children. And at the time, he's not solving any of the problems. So I am deeply concerned that he is incapable of doing the job."
