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

President Donald Trump signed two executive orders aboard Air Force One on Thursday evening.

One of the orders, titled "Making America Beautiful Again by Improving Our National Parks," outlines a policy aimed at the accessibility of America’s national parks. The EO suggests generating additional revenue by raising fees for foreign tourists.

"I just signed an executive order to raise entrance fees for foreign tourists while keeping prices low for Americans. The National Parks will be about America first," Trump recounted during his remarks in Des Moines, Iowa.

The White House celebrations for the Fourth of July will include several flyovers, including one featuring B-2 bombers. The president confirmed that the flyover will occur at the same time he signs his tax and spending bill that was passed by the House on Thursday.

“So we're signing at about five o'clock, and at about five o'clock we're going to have B-2s and F-22s and F-35s flying right over the White House,” Trump said. “So we'll be signing with those beautiful planes flying right over our heads, alright?”

Trump invited the B-2 pilots and crews who bombed Iran’s nuclear facilities last week to celebrate the holiday in Washington. Officials said Wednesday no public ceremony is planned and the pilots' identities are not being disclosed for security reasons.

Trump said he didn’t cut any deals with House holdouts to get his tax and spending bill passed.

“No deals. No deals. What I did is -- we talked about how good the bill is. I mean, that's a deal, I guess, when you think about it but, obviously, convince them, but it was not hard,” he said. “This is a great bill. This is going to be a great bill for the country.”

Rep. Ralph Norman, one of the holdouts, said earlier Thursday that Trump promised to “make the bill better” in the future when he told him about his concerns that not enough was being cut.

Asked about what it says about the power he’s amassed to get his megabill over the finish line, Trump said he believes he has more power now than ever before.

"I think I have more power now," Trump said as he headed for an event in Iowa Thursday afternoon. "I do, you know, I could say, 'Oh, gee, I don't know.' I think I probably do, because we've had a great record of success."

"You know, my first term was very, very successful. We had the greatest economy in the history of our country. I think we're going to blow it away this term,” Trump claimed.

"But, you know, we've, we've proven certain things. And, yeah, I think probably it's got more gravitas, more power," he added.
