Over the weekend, Department of Homeland Security Secretary Kristi Noem said the agency is investing $1 billion in airport security checkpoints around the nation.
"The new technology will include not only X ray technology to scan carry on bags, also checked bags, but also the physical technology that it takes to scan individuals," Noem said at a press conference at Harry Reid Las Vegas International Airport on Saturday. "You've all seen the ATS systems and the scanning technologies. All of those will be implemented, as well as more training into our officers."
Noem also handed out bonuses for TSA officers in both Las Vegas and Minneapolis on Sunday.
The Transportation Security Agency has been focusing on training agents with "hospitality" in addition to security.
"Not just facilitating individuals getting through security checkpoints, but how to help people that may be stressed in that type of a situation, people who may be nervous, flyers, how we can help them cope with that situation, anyone who may be having a mental health struggle, all of those are situations which our security officers face every single day. Is helping individuals feel much more comfortable while we make sure that we're also getting them screened into their flights on time," Noem said of those who might fly during the holidays.

President Donald Trump early on Monday said the "full benefit" of his tariff policies would take effect soon, bringing "unprecedented" wealth and national security.
He argued in a social media post that foreign buyers stockpiled inventory before his sweeping tariffs were put into place, allowing them to delay payments to the U.S., but, he said, that inventory will run out shortly and make way for record-setting revenue.
Trump also said he looks "so much forward" to the Supreme Court decision on his tariffs, which were put into place under the International Emergency Economic Powers Act. That 1977 bill in part allows the president, upon declaring a national emergency, to regulate certain international economic transactions that threaten national security. The statute never mentions duties or taxes.
The Supreme Court on Nov. 5 heard arguments over whether Trump exceeded his authority in imposing the tariffs. It's not clear when the court will issue an opinion, although a ruling is expected before the end of June 2026. The court accepted the Trump tariffs case on an expedited basis.
The government has already collected at least $89 billion from those tariffs, Customs and Border Protection data shows. That money might be refunded if the court rules against Trump.
