WATCH: Pentagon holds briefing as Israel’s Netanyahu makes first U.S. visit since Oct. 7 attack

Pentagon press secretary Pat Ryder will hold a news briefing on Tuesday as Israeli Prime Minister Benjamin Netanyahu visits Washington this week.

Watch in the player above.

The main purpose of Netanyahu’s visit is a speech to a joint meeting of Congress. But at stake, in meetings with administration officials, are hopes for progress in U.S.-led efforts to mediate an end to the nine-month Israel-Hamas war. The visit comes as the toll of Palestinians killed in Israeli strikes in Gaza nears 40,000. It’s also in a week when new deaths were reported among the surviving hostages — who include Israelis, Americans and other nationalities — held by Hamas and other militants since the first hours of the war.

Netanyahu planned his trip weeks before the ground abruptly started heaving under U.S. politics this summer. That includes a July 13 assassination attempt against Republican presidential nominee Donald Trump, and President Joe Biden’s decision Sunday to give up his faltering reelection campaign and endorse Vice President Kamala Harris for the presidency instead.

Protests are planned for Netanyahu’s planned speech to both houses of Congress on Wednesday.
