Health and Human Services Secretary Robert F. Kennedy Jr. confirmed Sunday that he is in West Texas today to "comfort" the family of an unvaccinated girl who died of measles.

On Sunday, the Texas Department of State Health Services said a second child had died from measles.

Kennedy said he "developed bonds with and deep affection for other members of this community" when he got to know the family of the first child who died from measles in February. That girl was also unvaccinated.

"My intention was to come down here quietly to console the families and to be with the community in their moment of grief," Kennedy said.

Kennedy also said he was visiting to learn how to better support public health officials on the ground, and said "the most effective way to prevent the spread of measles is the MMR vaccine."

Attorney General Pam Bondi said Sunday she expects Trump will "probably" leave the presidency following his second term -- even as she left the door slightly open toward him serving another four years in what she described as a "heavy lift" to amend the U.S. Constitution.

"President Trump has served one full term. He's on his second full term. He's a very smart man and -- we, I wish we could have him for 20 years as our president, but I think he's going to be finished probably after this term," Bondi said in an interview on “Fox News Sunday.”

"Probably?" host Shannon Bream asked.

"Well, the Constitution -- we'd have to look at the Constitution," Bondi replied. "It would be a heavy lift."

"And whether you get two thirds of the Senate and House to go along with you -- but is the concession that that's really the only way to do it?" Bream said.

"It'd be a heavy lift," Bondi responded.

Secretary of State Marco Rubio announced on X on Saturday that he was revoking all visas to South Sudanese passport holders "due to the failure of South Sudan's transitional government to accept the return of its repatriated citizens in a timely manner."

Nearly 2.32 million South Sudanese people, many of whom are women and children, had fled the country as of 2023 because of a rise in violence, according to the United Nations High Commissioner for Refugees.

It is the largest refugee crisis in Africa, according to the nonprofit organization.

The Justice Department has placed a government attorney on indefinite paid leave after he argued on behalf of the government on Friday in a lawsuit brought by a Maryland man who was deported to El Salvador in error, sources familiar with the matter told ABC News.

Sources said Erez Reuveni, acting deputy director for the Office of Immigration Litigation, was told by officials at at the DOJ that he was being placed on leave over a "failure to zealously advocate" for the government's interests.

The government is seeking to appeal an order from the judge who presided over Friday's hearing and ordered the department to facilitate the return of Kilmar Armando Abrego Garcia by Monday.

In Friday's hearing, Reuveni repeatedly struggled when pressed by Judge Paula Xinis for details surrounding Abrego Garcia's deportation -- and why the administration claimed it could not facilitate his return to the United States.

At one point in the hearing, Reuvani was asked by Xinis under what authority law enforcement officers seized Abrego Garcia.

Reuveni said he was frustrated that he did not have those answers.

"Your honor, my answer to a lot of these questions is going to be frustrating, and I'm also frustrated that I have no answers for you on a lot of these questions," Reuvani said.

When asked about what Wednesday's sweeping tariffs set to go into effect on Wednesday would look like, Trump said that Americans would "see in two days."

Though Trump was light on specifics, he seemed to indicate that the tariffs might be lower than those imposed by other countries on the U.S.

"So, whatever they charge us, we charge them. But we're being nicer than they were,” he said. “We have a lot of countries, friend and foe. I always say friend and foe, but the friend in many cases is worse than the foe. They took advantage of us. And, we are going to be very nice by comparison to what they were. The numbers will be lower than what they've been charging us, and in some cases, maybe substantially lower."

When asked whether any countries might be exempt from the reciprocal tariffs, Trump said "it depends," and seemed to indicate he wouldn't target countries that had smaller trade deficits with the U.S.

Asked by ABC News' Karen Travers if he’s heard any concerns from automakers about the pending tariffs, especially after a meeting today with the chairman of Stellantis, Trump said no.

“Well, I gave them a big break for a month. I didn't charge them anything, you know, for a big month, for that first month, and they brought a lot of material into this country, because they could bring it in with that tariff,” Trump said.

Travers also pressed Trump on news that China, South Korea and Japan are working together to respond to U.S. tariffs, asking if he was concerned that the tariffs would push allies closer to China. Trump said he was not aware of that news, but did brush off the concerns.
