(CNSNews.com) - Sen. Bob Corker (R-Tenn.), chairman of the Foreign Relations Committee, says it's about time the United States started pushing back on Iran over its ballistic missile launches as well as what Iran is doing in Yemen, Syria and elsewhere in the Middle East.

President Trump tweeted on Thursday: "Iran has been formally PUT ON NOTICE for firing a ballistic missile. Should have been thankful for the terrible deal the U.S. made with them!"

Corker said it appears to him that the Trump team is "together" on its Iran plan: "I actually applaud what is happening," Corker told MSNBC's "Morning Joe" on Thursday. "I strongly applaud it. My guess is, there is going to be bipartisan applause."

Corker said he was in National Security Director Michael Flynn's office Wednesday, the same day Flynn went to the White House briefing room to announce, "As of today, we are officially putting Iran on notice."

"I'm happy that General Flynn did what he did yesterday," Corker said.

Neither Trump nor Flynn have said what it means to put Iran “on notice,” but Corker said he believes the Trump administration has "thought this through, I think they have a plan, and to be honest, I'm pretty excited about it."

Corker noted that Trump frequently criticized the Iran nuclear deal on the campaign trail.

"But I think what's happened is, they've come into office, they've had the ability now to see intelligence, and they're probably even more upset about the lack of action over the last six or seven months, based on them knowing now...the former administration should have taken action, did not take action, and I think they're even more anxious to make sure that we push back against what Iran has been doing."

Corker also said it's "too early to talk about military options. I do think, on the other hand, when they threaten us in other ways…when they have their naval vessels threatening ours, and doing things, they need to be aware, there's a new day, and we're not putting up with things they've been doing in the region.

“I think you're going to see pushback, not only against the violations on the nuclear agreement, I think you're going to see, as there should have been all along, pushback against what they're doing in Yemen, what they're doing in Syria, what they’re doing in other places."

"Let them (Trump) roll out what they plan to do, Corker added, indicating that newly confirmed Secretary of State Rex Tillerson will have a hand in it.

"I certainly hope at a minimum we're looking at tougher sanctions on the nuclear issue, but also the other activities that are taking place in the region -- I think you’re going to see a coordinated effort sanctions-wise and other in multiple ways against Iran, as should be the case.”
