Rubio, Hegseth and Caine to address lawmakers

Hello and welcome to the US politics live blog.

With all members of Congress across both houses due to be briefed today on the Iran strikes, the Trump administration has presented a shifting new justification for its war.

Secretary of state Marco Rubio, defense secretary Pete Hegseth and general Dan Caine will brief the full membership of the House and Senate on Tuesday, with a possisble vote on parallel war powers measures to follow.

It comes after House speaker Mike Johnson suggested on Monday that the White House believed Israel was determined to act on its own, leaving the president with a “very difficult decision”.
