The Department of Health and Human Services directed recipients of grant funding from the Centers for Disease Control and Prevention to immediately halt all programs, personnel and activities related to "gender ideology," according to an email obtained by ABC News.

“You must immediately terminate, to the maximum extent, all programs, personnel, activities, or contracts promoting or inculcating gender ideology at every level and activity, regardless of your location or the citizenship of employees or contractors, that are supported with funds from this award,” the email stated.

“Any vestige, remnant, or re-named piece of any gender ideology programs funded by the U.S. government under this award are immediately, completely, and permanently terminated," it continued.

The latest directive from the HHS impacts any entity that receives CDC funds, such as local health departments and clinics, and it affects any programs supported by the nearly $4.5 billion spent by the CDC last year to aid health departments across all 50 states.

Dozens of Department of Education employees received letters on Friday night placing them on “administrative leave," effective immediately.

While no specific reason was given, employees told ABC News on Sunday that they believe the only common thread between them is that they attended a voluntary diversity training program in 2019, during President Donald Trump's first term.

ABC News has obtained the letter which states that the administrative leave notice is not for disciplinary purposes; rather, the letter said it's related to Trump’s executive order on diversity, equity, inclusion and accessibility. Employees were told to await “further guidance from OPM,” according to the letter, referencing the Office of Personnel Management.

Per the letter, employees will receive full pay and benefits through the end of the administrative leave, but they are not required to do work-related tasks during this time or come into the office. At the same time, the impacted employees had their government email access suspended.

Sheria Smith, the American Federation of Government Employees Local 252 president, told ABC News that over 50 employees in “extremely diverse roles” within the department had received the emails after regular business hours this weekend.

Smith said she fears more letters will be sent in the coming days.

ABC News did not receive an immediate response to a request for comment from the DOE.

In an interview that aired on "60 Minutes" on Sunday, former Republican Leader Mitch McConnell was openly critical of recent decisions by President Donald Trump and said he planned to be more outspoken about their differences of opinion now that he was no longer in a leadership role in the Senate.

McConnell sharply criticized the president imposing tariffs, especially on allied countries.

"It'll drive the cost of everything up. In other words, it'll be paid for by American consumers. I mean why would you want to get in a fight with your allies over this?" McConnell questioned.

McConnell often found himself at odds with Trump during his first term in the White House, he said, but claimed their relationship was all but severed after Jan. 6, 2021.

The former Senate leader reacted to Trump's sweeping pardons for the convicted rioters, saying, "I think pardoning people who have been convicted is a mistake."

President Donald Trump plans to speak with Canadian Prime Minister Justin Trudeau and Mexican President Claudia Sheinbaum on Monday morning, he told to reporters during a stopover at Joint Base Andrews on Sunday evening.

The calls are scheduled two days after he imposed 25% tariffs on both of the United States' neighboring countries.

Sheinbaum is also expected to deliver Mexico’s response to the tariffs in the morning, according to sources familiar with the situation.

Mexican President Claudia Sheinbaum has responded to President Donald Trump's move to impose 25% tariffs on all Mexican imports to the U.S.

In a lengthy statement in Spanish on social media platform X, Sheinbaum said she has instructed officials in her government to implement Plan B, "which includes tariff and non-tariff measures in defense of Mexico's interests."

The message did not provide any further details about the tariffs.

Sheinbaum said Mexico does not want confrontation with the U.S.

"We start from collaboration between neighboring countries. Mexico not only does not want fentanyl to reach the United States, but anywhere. Therefore, if the United States wants to combat criminal groups that traffic drugs and generate violence, we must work together in an integrated manner."

She proposed establishing a joint U.S.-Mexico working group, "with our best public health and security teams."

A fact sheet the White House sent out laying out the rationale for the tariffs alleged that the Mexican government was working directly with drug cartels.

"Mexican drug trafficking organizations have an intolerable alliance with the government of Mexico," the fact sheet stated. "The government of Mexico has afforded safe havens for the cartels…This alliance endangers the national security of the United States."

In a withering response to that charge, Sheinbaum said: "We categorically reject the White House's slander of the Government of Mexico for having alliances with criminal organizations, as well as any intention to interfere in our territory."
