What to know about Netanyahu's controversial DC visit

Israeli Prime Minister Benjamin Netanyahu's visit to Washington this week is looming as a fraught one between the two allies, coming at a moment of extreme political flux in the United States and wariness among American leaders about Netanyahu's history of interjecting himself into U.S. domestic politics.

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.
