Israel-Gaza updates: Israel strikes 'deep inside' Lebanon after deadly attack

Sen. Ben Cardin, D-Md., will preside over Prime Minister Benjamin Netanyahu's address to Congress on Wednesday, a source confirmed to ABC News.

Cardin, the chairman of the Senate Foreign Relations Committee, and House Speaker Mike Johnson, R-La., will be behind Netanyahu in the House chamber for the address.

Vice President Kamala Harris, who is the first in line to preside over the session, will be traveling on Wednesday and therefore not be in attendance.

A separate source confirmed to ABC News that Sen. Patty Murray, D-Wash. -- who, as the Senate president pro tempore, is second in line for presiding -- declined to preside.

He said they’ll talk about "how to advance in the critical months ahead the goals that are important for both our countries -- achieving the release of all our hostages, defeating Hamas, confronting the terror axis of Iran, and ensuring that all of Israel’s citizens can return safely to their homes in the north and the south."

Netanyahu added, "This will be an opportunity to thank him for the things he did for Israel in the war and during his long and distinguished career in public service, as senator, vice president, and president."
