Trump admin updates: Trump says tariff letters to be sent to 'various countries' on Monday

Ukrainian President Volodymyr Zelenskyy said on Friday that he and President Trump spoke by phone, writing on X that it was "very important and fruitful."

Zelenskyy said they discussed the Russian attacks overnight and that they agreed to work together to "strengthen protection of our skies."

The call came days after the Trump administration paused weapons shipments to Ukraine.

Zelenskyy said they also had a detailed discussion about potential joint defense industry projects with the U.S.

It suggests Ukraine is perhaps proposing to work with the U.S. to manufacture the weapons it needs, given Trump's reluctance to keep donating them.

President Trump landed in Washington, D.C. early Friday, taking questions from reporters as he returned from his Iowa victory lap for the megabill.

President Trump defended the merits of the bill, calling it "very popular" and claiming that the only poll on the matter was a "Democrat poll." He claims that what makes the megabill popular is that it will bring the "biggest tax cuts in our country's history," and that the tax cuts alone are what makes the bill popular.

Trump also boasted about his border numbers in the month of June, but says he wants to "keep them going up."

"We just want to see if we can keep going up. We have had great numbers," Trump said. "But we just want to keep them going up, right? That's all we can do."

At his rally in Iowa on Thursday, President Donald Trump kicked off "America 250" by giving a preview of some of the events that will take place to celebrate the 250th birthday of the U.S. next year.

“We will be orchestrating what we're calling the great American State Fair, and it will start right here in Iowa,” Trump announced.

Trump said that part of the celebrations would include a UFC fight on the White House lawn, an event that will be put on by UFC CEO Dana White.

"We're going to have a UFC fight. Think of this on the grounds of the White House,” he said. “We have a lot of land there."

Trump also announced a nationally televised sporting event featuring top-ranked high school athletes, spearheaded by Health and Human Services Secretary Robert F. Kennedy Jr.

Trump also previewed his National Garden of American Heroes, which will be “a vast outdoor park featuring statues of the greatest Americans who ever lived,” which will be funded through the megabill he is due to sign into law on Friday.

Speaking at the Iowa rally, President Donald Trump said the recent U.S. strikes on Iranian nuclear sites, followed by the passage of the megabill, has been the "best two weeks."

"Has anybody ever had a better two weeks?" Trump asked the crowd.

Trump again emphasized the strikes led to "complete obliteration" of Iran's nuclear facilities, dismissing questions about the effectiveness of the strikes.

The B-2 pilots who carried out the strikes are set to visit the White House on Friday for the July 4 holiday.

Trump also recounted conversations he said he had with Iran leading up to Iranian counterstrikes on a U.S. air base in Qatar.

“They called me to tell me they have to take a shot at us," Trump said. "This was Iran. Very respectful. That means they respect us because we dropped 14 bombs. They said ‘We'd like to take 14 shots at USA.’ 'Go ahead,’ I understand,’” Trump said before explaining the facility was emptied out ahead of the counter strike.

“They were a little nervous about doing it," Trump said. "I want to tell you. Can you imagine they were nice enough -- this is Iran -- to call me and tell me."
