The House of Representatives is banning staffers from using apps from ByteDance, the Chinese-owned parent company of TikTok, on official congressional devices, Axios has learned.

Why it matters: The government is in active litigation making the case that TikTok's ties to China represent a national security threat — an argument that could be undermined if congressional employees have associated apps on their phones.

A senior U.S. delegation arrived in Saudi Arabia on Tuesday for talks about the situation in Yemen and the recent escalation between Israel and Houthi rebels, three U.S. officials said.

Why it matters: Saudi Arabia has become more concerned in recent weeks about the rising tensions and being dragged into a renewed conflict in Yemen.

Venezuela's outsized role in U.S. politics is poised to grow further after autocrat Nicolás Maduro was declared the winner in a presidential election widely condemned as fraudulent.

Why it matters: Nearly 8 million Venezuelans have fled the crisis-stricken nation over the last decade. Maduro's re-election and the ensuing political unrest could exacerbate the refugee crisis in the final months before the U.S. election.

Congressional Republicans are pressing the Biden administration to impose harsh sanctions on Venezuela's government for allegedly "subverting" the results of the country's presidential election on Sunday.

Why it matters: Some Republicans have blasted Biden administration's deal with Venezuelan President Nicolás Maduro to ease sanctions on the country's oil and gas sectors in exchange for holding free and fair elections.

Israel experienced hours of chaos on Monday after far-right protesters encouraged by ultranationalist politicians from the governing coalition broke into a military base where Hamas militants are detained and another base hosting the Israel Defense Forces military court.

Why it matters: For 12 hours, Israel was immersed in the unrest as television networks broadcast live from the scene and the defense establishment and political system dealt with the unfolding events. The country's military leaders were forced to turn their focus from preparing for a possible strike against Hezbollah that could spark war on another front to protecting their own base from domestic turmoil.

NBCUniversal's coverage of the Paris Olympics is already worthy of a gold medal, just a few days into Games.

Why it matters: Few events are as important to the Comcast-owned media company as the Olympics, but recent Games had been beset by record-low ratings and bad optics.

The Biden administration thinks the scenario of an all-out war between Israel and Hezbollah is "exaggerated," White House spokesperson John Kirby said in a briefing with reporters on Monday.

Why it matters: The White House knows Israel is going to conduct a significant response against Hezbollah, but is trying to contain the situation as much as possible, U.S. officials said.

The Paris Olympic Games' first weekend finished with the U.S winning more medals than any other team, and it's the only nation so far with a medal haul in the double digits.

By the numbers: Team USA had 12 medals by the end of day two of the Olympics Sunday, picking up two golds in swimming and one in fencing. France has won the second most so far (eight medals, including three gold), followed by Japan (seven medals, including four gold).
