Trump admin updates: Trump says Venezuelan airspace should be 'closed in its entirety'

President Donald Trump said on Friday that any document signed by former President Joe Biden using an autopen "is hereby terminated."

"I am hereby cancelling all Executive Orders, and anything else that was not directly signed by Crooked Joe Biden," Trump posted on his social media platform.

It is unclear which orders Trump is referencing and how he is making those determinations. ABC News has reached out to the White House for more information.

Trump claimed that the people who "operated the Autopen did so illegally." But the Justice Department's legal counsel states that autopens are lawful for signing bills into law.

The president has repeatedly fixated on Biden's use of the autopen. In June, Trump claimed Biden aides illegally used the autopen to carry out "radical" policies and ordered the Justice Department and White House to investigate Biden’s mental state when he was in office. At the time, Biden issued a statement to ABC News calling the probe “nothing more than a mere distraction.”

"Let me be clear: I made the decisions during my presidency. I made the decisions about the pardons, executive orders, legislation, and proclamations. Any suggestion that I didn't is ridiculous and false," Biden said in the June statement.

Trump has said he has used an autopen for some trivial matters, but criticized its use for pardons.

In a post on social media late Wednesday, U.S. Citizenship and Immigration Services announced the "processing of all immigration requests relating to Afghan nationals is stopped indefinitely pending further review of security and vetting protocols."

The announcement came shortly after remarks by President Donald Trump regarding the shooting of two National Guard members in D.C. identifying the suspected shooter as an Afghan national who entered the U.S. in 2021.

Trump said the U.S. "must now reexamine every single alien from Afghanistan who has entered our country under (former President Joe) Biden and we must take all necessary measures to ensure the removal of any alien from any country who does not belong here or add benefit to our country."

Trump says that he will not invite South Africa to participate in next year's G20 Summit hosted at his Doral golf course and stop all payments and subsidies to the country "effective immediately."

"At the conclusion of the G20, South Africa refused to hand off the G20 Presidency to a Senior Representative from our U.S. Embassy, who attended the Closing Ceremony. Therefore, at my direction, South Africa will NOT be receiving an invitation to the 2026 G20, which will be hosted in the Great City of Miami, Florida next year," Trump posted on his social media platform.

"We are going to stop all payments and subsidies to them, effective immediately."

Trump refused to attend, or send a U.S. official to, the G20 summit this year in South Africa as he continues to amplify claims there have been targeted killings against white Afrikaners in the region.

A spokesperson for the Vice President JD Vance's office says that Vance and Army Secretary Dan Driscoll will meet privately at Fort Campbell on Wednesday afternoon, before Vance serves food to the troops for Thanksgiving. Driscoll will not participate in any of the public portions of Vance's visit to Kentucky.

Driscoll has been working on negotiations for the administration's Russia-Ukraine peace proposal. Driscoll held secret talks on Monday with a Russian delegation in Abu Dhabi in the United Arab Emirates to follow up on this weekend's talks with Ukraine in Geneva that were intended to move the peace process forward, a U.S. official told ABC News.

President Donald Trump said on Tuesday that he's directed Driscoll to meet with the Ukrainians and White House special envoy Steve Witkoff to meet with Russia's Vladimir Putin in Moscow.
