Trump admin live updates: Trump, Schumer trade barbs over Senate nominations

President Donald Trump is defending his use of tariffs just one day before his Aug. 1 deadline.

"Tariffs are making America GREAT & RICH Again," Trump wrote on his conservative social media platform. "They were successfully used against the USA for decades and, coupled with really dumb, pathetic, and crooked politicians, we're having a devastating impact on the future, and even the survival, of our country. Now the tide has completely turned, and America has successfully countered this onslaught of Tariffs used against it."

In a second post, Trump thanked lawyers working to defend his tariff plans. Trump's post comes as U.S. businesses and state leaders will argue in a federal appeals court on Thursday to nullify his tariffs.

"To all of my great lawyers who have fought so hard to save our Country, good luck in America's big case today. If our Country was not able to protect itself by using TARIFFS AGAINST TARIFFS, WE WOULD BE "DEAD," WITH NO CHANCE OF SURVIVAL OR SUCCESS. Thank you for your attention to this matter!" Trump wrote.

The Third Circuit Court of Appeals has denied the Trump administration’s attempt to re-detain Columbia University pro-Palestinian activist Mahmoud Khalil while it continues to appeal a federal judge’s decision to release him.

A panel of three judges found that the Trump administration did not demonstrate it would suffer “irreparable harm” if Khalil was not detained again.

The court also partially rejected the government’s request to pause U.S. District Judge Michael Farbiarz’s order, which reaffirmed that Khalil cannot continue to be detained solely based on Secretary of State Marco Rubio's assertion that his presence in the U.S. is harmful to the administration’s foreign policy priorities.

The same day Khalil was released on bail, the immigration judge overseeing his removal proceedings found him removable based on Rubio’s determination. Farbiarz found the immigration judge’s decision “directly inconsistent” with his previous order.

However, the appeals court on Wednesday did not order the immigration judge to consider Khalil’s request for a waiver of removability.

This case is widely thought to be headed toward the Supreme Court as the Trump administration has accused the District Court of overstepping its authority and intervening with the immigration judge’s attempts to remove him from the country.

Trump announced in a social media post a trade deal with South Korea in which it will receive a 15% tariff rate and have no duty on U.S. goods and open their market to U.S. goods completely.

"Additionally, South Korea will purchase $100 Billion Dollars of LNG, or other Energy products and, further, South Korea has agreed to invest a large sum of money for their Investment purposes. This sum will be announced within the next two weeks when the President of South Korea, Lee Jae Myung, comes to the White House for a Bilateral Meeting," Trump wrote in the post on his Truth Social social media platform.

President Trump is slapping tariffs on Brazil and sanctions on a Brazilian judge over what the White House says is a "politically motivated persecution" of former Brazilian president Jair Bolsonaro.

Trump signed an executive order slapping another 40% tariff on Brazil, bringing its total tariff rate to 50% when combined with the 10% baseline tariff. Trump took the action to "deal with recent policies, practices, and actions by the Government of Brazil that constitute an unusual and extraordinary threat to the national security, foreign policy, and economy of the United States," according to a White House fact sheet about the move.

The fact sheet said that the criminal charges against Bolsonaro's "politically motivated persecution, intimidation, harassment, censorship, and prosecution of former Brazilian President Jair Bolsonaro and thousands of his supporters are serious human rights abuses" have undermined Brazil's rule of law.

The tariffs do have carve-outs for some key imports. There are exemptions on goods including orange juice, aircraft and energy, which could reduce the impact of the duties.

That comes as the Treasury Department announced today sanctions on Alexandre de Moraes, a Brazilian Supreme Federal Court justice, who they claim has "used his position to authorize arbitrary pre-trial detentions and suppress freedom of expression."

"Alexandre de Moraes has taken it upon himself to be judge and jury in an unlawful witch hunt against U.S. and Brazilian citizens and companies,” Treasury Secretary Scott Bessent said in a press release. "De Moraes is responsible for an oppressive campaign of censorship, arbitrary detentions that violate human rights, and politicized prosecutions—including against former President Jair Bolsonaro."

Bolsonaro has been charged in Brazil for an attempted coup d état. Trump and Bolsonaro have long been close, Bolsonaro attempted to travel to the U.S. for Trump's inauguration in January of this year, but that request was declined by de Moraes.
