As Netanyahu arrives in Washington, Kamala Harris treads a careful path on Israel and Gaza

Harris insiders say she is more likely to engage in public criticism of the Israeli prime minister than Joe Biden and to focus attention on the civilian toll in Gaza

One of the key intrigues hanging over Benjamin Netanyahu's contentious visit to Washington this week is what kind of reception he will receive from the White House, and how he will be received by Joe Biden and his vice-president - and the likely Democratic party nominee - Kamala Harris.

For much of Monday, no meetings between Netanyahu and either Biden or Harris had been confirmed, even though the Israeli PM had already departed for the US and was scheduled on Wednesday to address a joint session of Congress at the request of the House leader, Mike Johnson, a Republican.
