The United States "made very good progress" in its discussions with Iran on Saturday, according to a Trump administration official.

"Today, in Rome over four hours in our second round of talks, we made very good progress in our direct and indirect discussions. We agreed to meet again next week and are grateful to our Omani partners for facilitating these talks and to our Italian partners for hosting us today," the official told ABC News in a statement.

In a statement to ABC News, White House press secretary Karoline Leavitt blasted the order from the Supreme Court and said the White House is confident the deportation actions by the administration are lawful.

"We are confident in the lawfulness of the Administration's actions and in ultimately prevailing against an onslaught of meritless litigation brought by radical activists who care more about the rights of terrorist aliens than those of the American people," she said in her statement.

In a 1 a.m. ruling, the Supreme Court blocked the deportations of Venezuelan migrants held in northern Texas under President Donald Trump's Alien Enemies Act executive order.

The court directed the Trump administration not to remove Venezuelans held in the Bluebonnet Detention Center "until further order of this court."

Justices Clarence Thomas and Samuel Alito dissented. Alito was slated to provide a statement about his dissent.

The White House and Justice Department did not comment on the ruling.

The American Civil Liberties Union filed an emergency appeal to the Supreme Court in its court battle against the administration, challenging the deportations.

"We are relieved that the Supreme Court has not permitted the administration to whisk them away the way others were just last month," ACLU attorney Lee Gelernt said in a statement.

President Donald Trump announced on Friday that his administration took a step toward making thousands of federal workers easier to fire by stripping them of civil service protections and reclassifying them as "at-will" employees.

"Moving forward, career government employees, working on policy matters, will be classified as 'Schedule Policy/Career,' and will be held to the highest standards of conduct and performance," Trump posted on social media.

"If these government workers refuse to advance the policy interests of the President, or are engaging in corrupt behavior, they should no longer have a job," he added. "This is common sense, and will allow the federal government to finally be 'run like a business.' We must root out corruption and implement accountability in our Federal Workforce!"

The new proposed "Schedule Policy/Career" classification will affect about 50,000 federal workers, or about 2% of the workforce, according to the White House. The workers "are not required to personally or politically support the President, but must faithfully implement the law and the administration's policies," the White House added.

The new rule proposed by OPM is not immediately reclassifying these workers. For the change to happen, Trump will need to sign an executive order after OPM issues a final rule.
