And for more on Congress's role in all of this, we are joined by our Capitol Hill correspondent, Lisa Desjardin.

So Lisa, let's talk about the policy involved here.

And who determines when the U.S. strikes another country?

What's the debate in Congress right now?

Yeah, it's basic civics.

Congress has the power to declare war.

But under Article 2, the president oversees military operations.

In reality, Congress has not declared war

since 1942, and it has been presidents acting unilaterally. It have been war actions for

the United States. Now, members of both parties for a long time have had a problem with this

in Congress, but it is usually only the opposition party that does anything about it or attempts

to challenge war powers.

And indeed, Democrats now are about to bring war power resolutions to the floor of both the House and the Senate.

The first one we expect to get a vote will be in the Senate.

But in the House, Speaker Johnson said today to reporters that he opposes any efforts to check the president right now.

I don't think this is an appropriate time for a war power's resolution and I don't think it's necessary.

Listen, for 80 years, presidents of both parties have acted with the same commander chief authority under Article 2.

But this is where the process matters. This is a privileged resolution. So Johnson may be

forced to have a vote on the House floor, and we do expect a forced vote on the Senate floor on

Iran this week. And that's with the Democratic senator from Virginia, Tim Kane, who introduced

that bill. Tell us more about that and how this will play out in the Senate floor. That's right.

I think the resolution speaks well for itself.
