Secretary of State Marco Rubio, Secretary of Defense Pete Hegseth, Chairman of the Joint Chiefs Dan Caine, CIA Director John Ratcliffe and Attorney General Pam Bondi will be on Capitol Hill on Monday evening to provide a closed briefing to top lawmakers on the actions in Venezuela, multiple sources confirmed to ABC News.

The Gang of 8, which includes the House and Senate majority and minority leaders and the chairs and vice chairs of the House and Senate Intelligence Committee, will receive the briefing as well as the top Republican and Democrat on the Senate Foreign Relations Committee, Senate Armed Services Committee, House Foreign Affairs Committee and House Armed Services Committee.

The briefing is expected to take place at 5:30 p.m.

This comes after Senate Minority Leader Chuck Schumer and House Minority Leader Hakeem Jeffries on Saturday called for the administration to immediately brief the Gang of 8 on Venezuela.

The Foreign Minister of Venezuela, Yván Gil, said in a post on Telegram on Sunday that the personal immunity of a sitting head of state has been violated, which constitutes a fundamental principle of international law.

"Whoever kidnaps a president kidnaps the sovereignty of a people," he said.

"The masks have fallen," Gil said. He went on to claim that the United States government is only interested in Venezuela's natural and energy resources.

Nicolás Maduro and his wife, Cilia Flores, are both scheduled to make their initial appearances in Manhattan federal court at noon ET on Monday before Judge Alvin Hellerstein.

Like her husband, Flores is in federal custody at MDC-Brooklyn.

It was not immediately clear whether either of them had retained legal counsel ahead of their arraignments.

Maduro and Flores are among six defendants named in a 4-count superseding indictment that accused them of conspiring with violent, dangerous drug traffickers for the last 25 years.

Maduro’s son, two high-ranking Venezuelan officials and an alleged leader of the Tren de Aragua criminal gang are the other defendants.

The operation to capture and bring Venezuelan leader Nicolas Maduro to the U.S. took months of planning with the Department of Defense, according to a joint statement from the agency and the Justice Department, FBI, and the Drug Enforcement Agency.

"Specialized FBI and DEA personnel, including tactical and transport teams, worked alongside DOW and our DOJ attorneys and other DOJ components to ensure the secure movement, control, and transfer of 2 high-risk defendants," the statement says, in part. "All personnel involved acted professionally, decisively, and in strict accordance with U.S. law and established protocols."

The statement further says the United States "pursued every lawful option to resolve this matter peacefully. Those opportunities were repeatedly rejected. The responsibility for this outcome rests solely with those who chose to continue criminal conduct rather than disengage."

"The mission was conducted to support an ongoing criminal prosecution tied to large-scale narcotics trafficking and related offenses that have fueled violence, destabilized the region, and contributed directly to the drug crisis claiming American lives," according to the statement.
