Once again, Pennsylvania Sen. John Fetterman has broken ranks with most members of the Democratic Party in offering praise and support for President Donald Trump’s decision to strike Iran’s sensitive nuclear sites on Saturday.

“As I’ve long maintained, this was the correct move by @POTUS. Iran is the world’s leading sponsor of terrorism and cannot have nuclear capabilities. I’m grateful for and salute the finest military in the world,” Fetterman posted on the X platform along with a screenshot of the president’s initial

Meanwhile, members of Congress from both parties had mixed reactions to the strikes, with several members grousing about which branch – the Legislative or the Executive – has the more significant war powers authority.

Most Republicans are willing to give great deference to President Donald Trump to strike Iran without Congressional authorization to hit sovereign territory inside another country,” Fox News reported Saturday evening.

“There are some concerns the President’s aggressive action could peel off some pro-MAGA supporters simply because Trump campaigned against getting involved in overseas conflicts,” the outlet said. “There are also divisions among Democrats. Pro-Israel Democrats have been calling for the U.S. to strike Iran because of the threat it poses to Israel.”

Regardless, lawmakers from both parties remain concerned about potential retaliation from Iran and its proxies, including the possibility of attacks on U.S. soil by sleeper cells, Fox added.

Members of Congress will seek a clear understanding of the risks facing the United States as it becomes more involved in the conflict, as well as insight into the administration’s planned strategies moving forward. CIA Director John Ratcliffe reportedly plans to brief the entire Senate on Tuesday, according to reports.
