Trump 2nd term updates: Trump attends the Super Bowl

Transportation Secretary Sean Duffy addressed officials at the AASHTO Washington Briefing attendees Wednesday afternoon, expressing a desire for "aggressive change" and outlining some of the plans he has for the Transportation Department, particularly in regard to working with DOGE to upgrade aviation systems that was announced today.

"We're going to remake our airspace, and we're going to do it quickly, and we have the support of the Congress, I think, right now to say, you know what, we're using, like 1960s, World War II technology in much of the components of the airspace," Duffy said. "We're going to upgrade it and make sure that America has the most innovative, technologically advanced air system, air traffic control system. That's going to make it safer, and it's going to make it more efficient.”

Duffy said he spoke with Musk Tuesday, calling him a "pretty remarkable guy" who "thinks differently than … probably a lot of us."

He also spoke about the investigation the DOT will have to examine military helicopter operations, improve safety and address air traffic control shortages.

Duffy said the department will consider whether military helicopters should be restricted to different times of the day -- or whether they should be flown at all.

"Get in a damn suburban and drive you don't need to take a helicopter. We need a whole upgrade of the airspace," he said.

Trump signed an executive order banning transgender athletes in women's sports Wednesday afternoon, telling the crowd, "The war on women's sports is over," and fulfilling a promise that was at the center of his 2024 campaign.

"We've gotten the woke lunacy out of our military. And now we're very importantly getting it out of women's sports," he said in his opening remarks.

The order will establish sweeping mandates on sex and sports policy and will direct federal agencies, including the Department of Justice, to interpret federal Title IX rules as prohibiting the participation of transgender girls and women in female sports categories, according to a White House document on the executive order obtained by ABC News.

As House Speaker Mike Johnson was meeting with Treasury Secretary Scott Bessent on Republicans' plan on taxes, two House Democrats -- Reps. Judy Chu of California and Gwen Moore of Wisconsin -- barged into the speaker’s office to confront Johnson about the Department of Government Efficiency's access to Treasury Department payment systems.

"This is unprecedent. It is illegal," Moore said.

"Now we have a young man who has walked into the Treasury Department -- stuck in a thumb drive that can be used on remote laptop computers. And we don’t know why they’ve accessed this information, what information that they have, including sensitive military spending and activities. We don’t know. And what was most disturbing to me is that the speaker has no idea what they are doing," Moore added.

Chu said she got in the speaker’s office right behind Moore -- who was confronting Johnson about the treasury secretary.

Johnson paused his meeting with Bessent to speak with the two Democrats in his private office.
