President Trump appeared to suggest that Dr. Ronny Jackson, his pick to take over the Department of Veterans Affairs, might want to withdraw his nomination, amid allegations being investigated by the Veterans' Affairs Committee. While Mr. Trump told reporters he hadn't heard of any particular allegations leveled against Jackson and said he would "always stand behind him," he said he also asked Jackson, "What do you need this for?" "I don't want to put a man through a process like this. It's too ugly and too disgusting, so we'll see what happens," Mr. Trump said at a joint press conference with French President Emmanuel Macron.

"If I were him...I wouldn't do it," the president added. Jackson was the president's choice to take over the role from Secretary David Shulkin, whom he fired last month. Mr. Trump said Jackson was "too fine a person" but added that it was ultimately Jackson's decision if he wants to remain the nominee.

On Tuesday, Senators Johnny Isakson, R-Georgia, and Jon Tester, D-Mont. announced that Jackson's confirmation hearing on Capitol hill would be postponed in light of allegations that include fostering a "hostile work environment and "excessive drinking on the job."

The president also acknowledged concerns of Jackson's lack of experience to lead the VA, but said "nobody has the experience" to lead as large a hospital system as the VA.

Meanwhile, both Macron and Mr. Trump highlighted their differences on the Iran nuclear deal, but Macron expressed interest in working on a "new deal with Iran."

He said the current pact was not a "sufficient deal" but said the two leaders were able to have "frank discussions" on the issue.

However, Macron embraced aspects of the current deal -- for instance, the restriction of Iran's nuclear activity until 2025. He favors a new deal that blocks Iran's nuclear activity through 2025 and also contains Iran's activities in the region. Macron also suggested adding limitations on Iran's ballistic missile program.

"It's about respecting the sovereignty of the states in the region," added Macron. "It's not about tearing apart an agreement but building something new that will cover all of our concerns."

But Mr. Trump was quick to slam the deal again, deriding it as bad for the U.S. He issued a stern warning to Iran's leadership: "We're going to see what happens on the 12th, but Iran threatens us in any way, they will pay a price like few countries have ever paid."

"It will be possible to do a new deal with solid foundations because this is a deal with decayed foundations. It's a bad deal, it's a bad structure, it's falling down and it should have never ever been made," said Mr. Trump.
