Pentagon officials reportedly informed lawmakers Tuesday that the first six days of the Iran war have cost taxpayers more than $11.3 billion.

The estimate was provided to senators by War Department officials during a closed-door briefing on Operation Epic Fury, according to multipleoutlets, citing anonymous sources.  

"We do not comment on closed-door discussions or matters,” a Pentagon spokesperson told NBC News.  “Regarding the cost of Operation Epic Fury, we won't know the cost until the mission is complete."

The US and Israel launched airstrikes against targets in Iran on Feb. 28.

President Trump revealed Wednesday that he’s been briefed on the possibility Iranian terrorist sleeper cells could be activated to attack Americans.

The president indicated he was aware of an alarming FBI memo issued to law enforcement in California, warning that Iran could deploy drones from a vessel off the Golden State coastline to attack the mainland. 

“It is being investigated but you have a lot of things happening, and all we could do is take them as they come,” Trump told reporters after arriving back in Washington after a trip to Kentucky.

“The war itself is being prosecuted as well as anyone has ever seen,” the president added.

He blamed former President Joe Biden for the potential presence of Iran-aligned terrorists in the US. 

“I have been [briefed on Iranian sleeper cells] and a lot of people came in through Biden with his stupid open border, but we know where most of them are,” Trump said.  

“We got our eye on all of them, I think.” 

At least one person is dead and two oil tankers are ablaze in the Persian Gulf after a suspected Iranian attack on the vessels.

Explosive-laden Iranian boats reportedly struck the two tankers on Wednesday, Reuters reported, citing the initial findings of an Iraqi-led investigation into the fires. 

Farhan al Fartousi, the director general of the Iraqi Ports Company, told CNN that the 38 foreign crew members had to be rescued from the damaged ships after the "explosions."

Footage of the fires show the flames spreading in the surrounding water, a sign oil is leaking from the massive tankers, which were anchored alongside each other prior to the attack, according to CNN. 

The Maltese-flagged Zefyros and the Marshallese-flagged Safesea Vishnu were the targeted tankers, the outlet reported.

The registered owner of the Safesea Vishnu is US-based company Safesea Transport Inc., and the Zefyros is owned by a company in Greece.

President Trump brought boxer Jake Paul on stage during a rally in Hebron, Ky., on Wednesday, and predicted the social media star will someday run for office.

“I'm going to make a prediction that you will be, in the not too distant future, running for political office,” Trump said. 

“And you have my complete and total endorsement,” the president added. 

Paul, 29, was born and raised in neighboring Ohio.

He told the crowd that the president had taught him the value of “courage” and to “never back down from a fight.”  

“We need more factories like this thriving all over the country,” Paul said. “And I know [Trump’s]  going to be the one to bring that here to us.”

He added, “I know God is with us. I know he wants us on the right side of history, and everyone here has to do their part. And God's got us. Trump's got us. God bless.”

Dr. Mehmet Oz came to the rescue of an elderly woman who fainted during President Trump's rally in Kentucky.

The woman was standing behind Trump when the incident occurred. Trump stopped his remarks and called for her to get help.

Oz, who serves as Trump's Administrator for the Centers for Medicare & Medicaid Services, came to the rescue.

"It's Dr. Oz. Can you believe it?," Trump said.

When the woman stood up, Trump raised his hands in victory.

"He's a good doctor. Thank you, Oz," the president said before returning to his remarks.

President Trump used his rally in Kentucky to slam Rep. Thomas Massie as a disloyal loser who needs to be voted out of office immediately.

"He is the worst person," Trump said as he went on a long riff against Massie. "There's something wrong with him."

"I just can't stand this guy."

Trump described the seven-term Republican congressman is a "disaster" for Republicans. The president has endorsed Massie's opponent, Ed Gallrein, in the May primary.

"We got to get rid of this loser," Trump said of Massie. "This guy is bad. He's disloyal to the Republican Party. He's disloyal to the people of Kentucky, and most importantly, he is disloyal to the United States of America, and he's got to be voted out of office as soon as possible."

Whereas Gallrein, Trump noted, has his "complete and total endorsement." The president gushed over the former Navy Seal as a great patriot and praised him as "strong as hell. He shook my hand. My hand is still recovering."

President Trump slammed California Gov. Gavin Newsom as unfit for the White House because he has "mental problems."

Using his "Gavin Newscum" nickname, Trump said the governor "admitted he has mental problems, that he's not a smart person."

In his memoir, "Young Man in a Hurry," Newsom wrote about his struggle with dyslexia, a common learning disability.

"He's unable to read a speech, he can't read, and all of the other things he said. He said he has a lot of mental problems," Trump said of Newsom.

"Nothing's wrong with it, but I don't want the President of the United States to have a cognitive deficiency," Trump said, adding: "When he admitted this, I said, I think he just lost the Democrat nomination."

President Trump revealed that he was presented with 20 potential names for the Iran war before settling on Operation Epic Fury.

"They gave me a list of names," Trump said in Kentucky, quoting aides as telling him, "Sir, you could pick the name you like, sir."

"I said, 'The name of what?' 'The name of the attack on Iran, sir.' And they gave me, like, 20 names, and I'm like falling asleep. I didn't like any of them. Then I see Epic Fury. I said, 'I like that name.'"

President Trump said he regretted the US military sinking Iran's navy rather than capturing the ships — and that a general defended the action by saying it was "more fun."

"[The US military] knocked out 54 ships in two days. And they're real ships," Trump said.

"In fact, I got angry at my people. I said, 'Are they good?' 'Yeah, they're warships.' I said, 'Why the hell did we kill them? Why didn't we just capture them and use them in our Navy?' They said, 'They wouldn't have qualified for that.'"

Trump added: "But I got a little upset with my people. I said,' Why do we have to knock them?' And actually, one of my general said, 'Sir, it's a lot more fun doing it this way.'"

The US military's ship-sinking included the first use of a torpedo since World War II.

Trump also noted the recent action to sink alleged Iranian mine-laying vessels in the Strait of Hormuz.

"You know, they wanted to drop some mines, very friendly people — mines, so boats blow up.... we knocked out 31 of them," Trump said.

President Trump said Wednesday that the US must "finish the job" before ending the war on Iran.

"We don't want to leave early, do we? We got to finish the job right. We don't want to go back," Trump said during a speech in Kentucky — after previously floating a timeframe of four weeks or less.

"Over the past 11 days, our military has virtually destroyed Iran — tough country," he added.

Trump earlier in the day refused to say if he would call off the US-Israeli operation before assassinating hardline new Supreme Leader Mojtaba Khamenei, who replaced his father Ali after his Feb. 28 death.

President Trump bragged that he is a leader who finally puts American workers first.

"After so many years of politicians who sold out the working men and women of our country, we finally have a president who puts American workers - you - first," Trump said to great applause at the Verst Logistics, an order fulfillment center in Kentucky.

Trump is in Kentucky to tout how he's improving affordability for Americans.

President Trump said he "loved" watching the backlash against Barack Obama for taking potshots at him during Jesse Jackson's memorial service.

"He spoke, and it was like a political hit job, and the family of Jesse Jackson got angry as hell at him," Trump said during a rally in Kentucky. "I loved watching that."

Obama didn't say Trump's name during his eulogy for the longtime civil rights leader, but it was clear who he was talking about when he said: “Each day we wake up to some new assault on our Democratic institutions, another setback to the idea of the rule of law, an offense to common decency."

Jesse Jackson's son expressed his anger with Obama and other speakers for using their time to criticize Trump.
