Iran and the United Nations’ nuclear watchdog are still negotiating over how to implement a deal struck last year to expand inspections of the Islamic Republic’s rapidly advancing atomic program. The acknowledgment on Tuesday by the International Atomic Energy Agency’s leader Rafael Mariano Grossi shows the challenges his inspectors face, years after the collapse of Tehran’s nuclear deal with world powers and the wider tensions gripping the Mideast over the ongoing Israel-Hamas war. Grossi has already warned that Tehran has enough uranium enriched to near-weapons-grade levels to make “several” nuclear bombs if it chose to do so. He has acknowledged the agency can’t guarantee that none of Iran’s centrifuges may have been peeled away for clandestine enrichment.

If it feels like TikTok has been around forever, that’s probably because it has, at least if you’re measuring via internet time. What’s now in question is whether it will be around much longer and, if so, in what form? The Chinese social video app merged in 2017 with the competing app Musical.ly, which also launched in China.

Senate Republicans are returning to a strategy they hope could neutralize their Democratic rivals' financial edge: Find rich people to run. But wealthy candidates running in Montana, Ohio, Pennsylvania and Wisconsin present a fresh set of challenges. One is hoping to recoup his own money before collecting resources for the fall race with well-funded Democrats. Others face questions about their past or where they live and spend most of their time. In each case, the relative unknown GOP contender is in a state critical to the party's chances to reclaim a Senate majority and is challenging a well-established, robust fundraiser seeking a third or fourth term in the closely divided Senate.

President Joe Biden has recognized the United States Military Academy with the Commander-in-Chief’s Trophy for besting other service academies in football. Army beat both the U.S. Naval Academy and the U.S. Air Force Academy during last year’s season. The West Point, New York-based college posted an overall win-loss record of 6-6, including a 57-point victory over Delaware State University, one of Biden’s favorite schools. The Air Force Falcons have won the trophy 21 times, compared with 16 for the Navy Midshipmen and 10 for the Army Black Knights.
