Former Vice President Mike Pence said on “State of the Union” Sunday that if Israel’s attack doesn’t somehow convince Iran to make major concessions in Trump’s diplomatic attempt to end its nuclear program, then the United States should be prepared to join the conflict.

President Trump opposed a recent Israeli plan to kill Iran's Supreme Leader Ayatollah Ali Khamenei, three U.S. officials told CBS News on Sunday.

Iran and Israel continued on Sunday their aerial attacks, which began Friday with a series of Israeli strikes on Iran.
