When asked about reports that the U.S. military killed two survivors of an earlier strike on a boat suspected of ferrying drugs in the Caribbean Sea in September, House Speaker Mike Johnson said he is "not going to prejudge any of that."

"In a preliminary review, the admiral who ordered the second strike thought it was necessary to complete the mission," Johnson said, referring to Adm. Mitch Bradley. "He's highly decorated, highly respected admiral in the Navy and he made that call."

Johnson said he has not reviewed the "scope of the mission" of "that particular strike," but he said that the incident will be something that "Congress will look at." He added that "second strikes are not unusual."

"I think it's very important for everybody to reserve judgment and not leap to conclusions until you have all the facts, and that's what we'll be uncovering," Johnson told reporters on Tuesday.

House Speaker Mike Johnson was asked about the House's plan to extend health care subsidies for Affordable Care Act beneficiaries after a reporter said two Republican members said "House Republicans are likely to get on board" with a deal.

The speaker could not confirm that update only saying that the Republicans "are moving forward" and that health care was a "complex issue."

"I can't project in advance what that will be because I don't know what the consensus is in that room," Johnson said of the plan. "But you will see our sleeves rolled up and that work being done in earnest this week as we bring all that together."

Defense Secretary Pete Hegseth put out a statement Monday night on his personal X account backing Adm. Mitch Bradley, the head of the United States Special Operations Command, who the White House claims ordered a second controversial strike on an alleged boat in September.

"Let’s make one thing crystal clear: Admiral Mitch Bradley is an American hero, a true professional, and has my 100% support. I stand by him and the combat decisions he has made — on the September 2 mission and all others since," Hegseth said in his post.

One person familiar with details of the incident confirmed to ABC News that there were survivors from the initial strike on the boat and that those survivors were killed in subsequent strikes.

While Americans were enjoying their Thanksgiving holiday, wholesale giant Costco filed a lawsuit against the Trump administration for a "full refund" for the tariffs the company paid.

"This separate action is necessary, however, because even if the [International Emergency Economic Powers Act] duties and underlying executive orders are held unlawful by the Supreme Court, importers that have paid IEEPA duties, including Plaintiff, are not guaranteed a refund for those unlawfully collected tariffs in the absence of their own judgment and judicial relief," the lawsuit filed in the Court of International Trade on Friday said.

While most lawsuits against the tariffs come from small businesses, Costco is seeking a refund for the tariff payments they incurred. Congress, not the president, has the power to impose tariffs, the lawsuit said.

The Court of International Trade "have agreed the IEEPA duties are not authorized," the lawsuit said.

This lawsuit is identical to other suits filed by American companies challenging the legality of Trump's IEEPA tariffs -- including one currently pending a decision at the U.S. Supreme Court.
