The U.S. has built roughly 50 miles of primary border wall along the southern border, 5.5 miles of buoy barriers in the water and 13.2 miles of secondary barriers, Customs and Border Protection commissioner Rodney Scott told Congress on Thursday.

Anthropic on Thursday released Claude Opus 4.7, a meaningful upgrade to its flagship AI model with better coding, sharper vision and a new ability to double-check its own work.

Why it matters: Anthropic publicly conceded that the new Opus model does not match the performance of Mythos, a highly advanced system that the company hasn't released to the public due to safety concerns.

Health Secretary Robert F. Kennedy Jr. will face Congress for the first time in more than six months on Thursday with his autonomy and political influence in a very different place.

Why it matters: As the White House tries to reel in his agenda, Kennedy is expected to face a gauntlet of questions about vaccines, autism and other hot-button issues at the first of seven hearings over this week and next.
