Trump admin live updates: Gov. says 'no need' after Trump directs troops to Portland

On ABC's "Good Morning America" on Tuesday morning, ahead of President Trump's speech to the United Nations General Assembly, Secretary of State Marco Rubio defended Trump's handling of the ongoing conflicts across the world -- including Russia's invasion into Ukraine and the conflict between Israel and Gaza.

On USAID cuts, when pressed if the administration's decision to severely cut foreign aid and dismantle the agency responsible for administering humanitarian aid and assistance to foreign countries has led to deaths around the world, Rubio pushed back and said the blame should fall on other countries who don't put up enough foreign aid.

"That's ridiculous. They died because England didn't give enough money, or Canada didn't give more or China didn't. Let's blame the other countries that don't do any foreign aid. How about China? It's the second largest economy in the world and they don't give money?" Rubio said.

"I think anybody who tells you that somehow the United States, if we cut a dollar somehow we are responsible for some horrific thing going on in the world, is just not true," he said.

"No one has died because the United States has cut aid, no," Rubio declared. "We are going to continue to do it, but we will do it the right way and in a responsible way. We aren't going to continue to pour billions of dollars out the door of American taxpayer funds for programs that don't work. And in some cases, flat-out corrupt."

Trump signed an executive order designating Antifa as a "domestic terrorist organization.”

The order directs federal agencies to "utilize all applicable authorities to investigate, disrupt, and dismantle any and all illegal operations — especially those involving terrorist actions — conducted by Antifa or any person claiming to act on behalf of Antifa."

The order also directs any necessary investigations and prosecutions of "those who fund such operations."

The order that Trump signed describes the organization as one that "recruits, trains, and radicalizes young Americans to engage in this violence and suppression of political activity, then employs elaborate means and mechanisms to shield the identities of its operatives, conceal its funding sources and operations in an effort to frustrate law enforcement, and recruit additional members."

The order also claims that antifa members coordinate with other organizations "for the purpose of spreading, fomenting, and advancing political violence and suppressing lawful political speech."

"This organized effort designed to achieve policy objectives by coercion and intimidation is domestic terrorism," the order said.

It is not immediately clear how the domestic terrorist organization designation would be made for antifa, which is an umbrella description for far-left-leaning militant groups opposing fascists and neo-Nazis. Antifa does not have a publicly known centralized structure or leadership.

Lindsey Halligan was officially sworn in as the interim U.S. Attorney for the Eastern District of Virginia, Attorney General Pam Bondi announced on social media Monday.

Halligan, who most recently worked in the White House staff secretary's office, represented President Trump for a time during the classified documents investigation.

Trump said Saturday that he would appoint his former attorney to lead the key federal prosecutor's office after the previous head, Erik Siebert, resigned his position amid pressure from Trump administration officials to bring a criminal case against New York Attorney General Letitia James.

President Trump made an announcement from the Oval Office on autism, flanked by Health and Human Services Secretary Robert F. Kennedy Jr. and Centers for Medicare & Medicaid Services Administrator Mehmet Oz.

"Today, we're delighted to be joined by America's top medical and public health professionals as we announced historic steps to confront the crisis of autism. Horrible, horrible crisis," Trump said.

He and his top officials stated the use of Tylenol during pregnancy may be linked to an increased risk of autism.

Trump said the Food and Drug Administration will begin notifying physicians immediately that it is "strongly recommending that women limit Tylenol use during pregnancy unless medically necessary."

"They are strongly recommending that women limit Tylenol use during pregnancy unless medically necessary," Trump said. "That's, for instance, in cases of extremely high fever."

Studies on this question have not shown a direct cause and effect. Some studies point to a possible link, but major medical groups have evaluated the evidence and continue to recommend acetaminophen as the safest painkiller during pregnancy.
