In an interview on NBC News' Meet the Press, Republican Senator Lindsey Graham justified Trump's decision to order military strikes without a congressional sign-off.

The plan votes to curb Trump's war powers would be the latest test in a largely Democratic effort to prevent the president from further military action across the world without congressional authorization.

It will also be a long shot.

For years, it has been a challenge for Congress to pass such a resolution because in 1983, the Supreme Court ruled that the president could veto them.

That's what happened when two similar resolutions passed during Trump's first term in office.

Some Iranian Americans across the country are feeling conflicted about this weekend's military strikes and the killing of Ayatollah Ali Khamenei.

While there's uncertainty and anxiety, for many there is also hope and cause for celebration.

That's the sound of Iranians in the streets of Los Angeles on Saturday as they welcomed the news that Iran could be on the doorstep of significant changes.

That was Mike Casaruni and Sagar Fani-Salik speaking to USA Today and CBS News in Los Angeles as they celebrated.

Corinne Patel is a reporter for the Los Angeles Times.

She notes that by 2019, more than half of Iranian immigrants to the U.S.

lived in California, and about 30 percent of them are in L.A.

County.

Much of LA's Iranian-American community reside in Westwood, a neighborhood that's been dubbed Tarantulas.

There are recent immigrants, as well as those who have lived in the country for decades.

Residents in the area spoke to Patil about how they are feeling in this moment.

Patel says she was reporting from a cafe in Westwood on Saturday when people began learning about what was unfolding in Iran in real time.

It wasn't just older Iranians that were excited.

Patil says younger generations were celebrating too.

Iranians gathered to celebrate in other cities also.
