Iran live updates: 7th killed service member is identified

Reza Pahlavi, the exiled former crown prince of Iran, said in an interview with "60 Minutes" on Sunday that he wants to be a "transitional leader" in Iran -- not "the future king or future president."

"They trust me as a transitional leader, not as the future king or future president or future whatever. I'm totally focused on my mission in life, which is let me bring the country to a point that they can make that free choice. That would be enough for me having said mission accomplished," Pahlavi said.

He said that he imagines a future where Iran is at peace with Israel, saying, "The strategic importance of having a partnership with Israel is critical."

Pahlavi also said that the nation's nuclear program should be "totally dismantled."

Pahlavi's father, Mohammad Reza Pahlavi, was the last shah of Iran. In 1979, he left Iran amid rising political tension. Ayatollah Khomeini came to power in 1979, following the success of the Iranian Revolution.

President Donald Trump returned to the White House on Sunday night from Mar-a-Lago, but he did not take questions from reporters about the operation in Iran or the recent U.S. casualties.

The president instead went to the Rose Garden to inspect newly installed statues of the Founding Fathers.

"Unbelievable statues. You'll see. Come and look at them," he told reporters.

On a call with Republicans on Sunday, House Speaker Mike Johnson told lawmakers a vote on the war powers resolution will likely be held on Thursday, two sources told ABC News.

Democrats and a handful of Republicans have demanded a vote on the resolution, which would require Congressional approval before the president orders any further military action in Iran. The measure is sponsored by Rep. Ro Khanna, D-Calif., and Rep. Thomas Massie, R-Ky.

ABC News has learned that Republican leadership is urging members to vote against it. Johnson also reminded Republicans on the call that attendance is important. With a razor-thin majority, Johnson can only afford to lose one vote if all members are voting and present.

While there is some bipartisan support for the war powers resolution, Republicans have the majority in the House and the president has veto power.

Johnson also told Republicans he plans to hold another vote this week on Dept. of Homeland Security funding, as the partial government shutdown continues.

The Gang of 8 and key leaders of national security committees are expected to receive a classified briefing on Iran from Trump administration officials on Monday, multiple sources told ABC News.

Members of the Gang of 8 include the top bipartisan House and Senate leaders and the chairs and ranking members of the House and Senate intelligence committees.

As ABC News previously reported, the House and Senate will receive a classified briefing from the administration on Tuesday.
