Trump continues to waiver back and forth on trade negotiations, saying on Tuesday that he is not interested in extending the tariff deadlines for countries that don't meet his July 9 deadline. It was just Friday that he suggested the deadline could be extended. Now he claims, he's planning to implement his reciprocal tariffs.

"Mr. President, are you thinking of extending the pause on tariffs beyond July 9?" a reporter asked him as he took questions on Air Force One.

"No. I'm not thinking about the pause. I'll be writing letters to a lot of countries. And I think you're just starting to understand the process," the president responded.

Trump slammed negotiations with Japan, saying he doesn't think a deal will be able to get done and noting that he'll be sending them a letter imposing tariffs soon. He later added that the United States could soon secure a trade deal with India that would allow Americans to "go in and compete" in order to impose fewer tariffs.

Republican Sen. Lisa Murkowski released a lengthy new statement on her vote in support of President Trump's domestic policy bill, which narrowly passed the Senate earlier Tuesday.

Calling it "one of the hardest votes" she has taken during her time in the Senate, the Alaska lawmaker explained her thinking behind voting for the bill in the end, despite her many concerns over cuts to Medicaid and food stamps. She noted it is the "people of Alaska that I worry about the most."

“But, let’s not kid ourselves," she continued. "This has been an awful process -- a frantic rush to meet an artificial deadline that has tested every limit of this institution. While we have worked to improve the present bill for Alaska, it is not good enough for the rest of our nation -- and we all know it."

“My sincere hope is that this is not the final product. This bill needs more work across chambers and is not ready for the President’s desk. We need to work together to get this right.”

The House Rules Committee convened on Tuesday afternoon to markup the Senate version of Trump's sweeping domestic policy bill. The markup is expected to last for hours.

"H.R.1 has returned to the people's House with final consideration," Rules Committee Chair Virginia Foxx said as she kicked off the markup. "And while I don't often think that the other body improves our legislation, it's important to recognize that much of what the House included in H.R.1 when we initially passed, it is still included."

"A failure to pass this legislation, carries with it, serious negative implications, not only for hardworking taxpayers, but also the nation," Foxx added.

Rules Committee ranking member Jim McGovern, a Democrat, said if the "ugly bill" passes in the House, "it's going to get a lot uglier when people realize what's in it, and not even Donald Trump's new $300 bottle of cologne will cover the stench."

"We are here today on a bill that just dropped from the Senate hot off the press, passed only an hour ago," McGovern said. "It's massive here. It is nearly 1,000 pages long, and I've got to ask: Have any of you read it this time? Because last time we met on this legislation, many of our Republican colleagues had not."

Senate Majority Leader John Thune, celebrating after steering the approval of President Trump’s megabill, nodded to all of the “work” that went into its passage.

“This doesn't happen easily, for sure, and in this case, it took a lot of time and probably a lot less sleep than I think most people were hoping for. But in the end, we got the job done, and we're delighted to be able to be partners with President Trump and his agenda, an agenda that is the right one for the American people, the one that they voted for last November," he told reporters at the Capitol.

Thune also acknowledged the difficulty House Republicans might have in passing the package as it now heads their way, but said he delivered them a “strong product.”

“Well, we'll see. I mean, you know how hard it was to pass it -- I think the House, I appreciate the narrow margins they have over there … but I think we gave a really strong product,” he said.

“I think we took what they sent us and strengthened and improved upon it. And so I'm hopeful that now, when it gets sent over there, as they deliberate about how they want to handle it, they'll find the goals that are necessary to pass it,” Thune added.
