Russian President Vladimir Putin offered his first public remarks after the Wagner Group attempted to march to Moscow and overthrow the government.

In a pre-recorded video statement, Putin thanked the Russians for their endurance, solidarity and patriotism during the ordeal and claimed that any blackmail attempt was doomed to fail.

Putin said an armed rebellion would have been suppressed.

"The organizers of the rebellion, betraying their country, their people, betrayed those who were drawn into the crime. They lied to them, pushed them to death, under fire, to shoot at their own," Putin said.

The Russian president noted that the majority of Wagner fighters were "patriots."

"I thank those soldiers and commanders of the Wagner Group who made the only right decision," Putin said. "They did not go to fratricidal bloodshed, they stopped at the last line."

Putin offered Wagner Group members who participated in the rebellion the option of joining the defense ministry or other law enforcement agencies or returning home.

President Joe Biden spoke out addressed the Wagner Group's actions over the weekend.

He said the U.S. and its allies convened on Friday when the rebellion began.

"They agreed with me that we had to make sure we gave Putin no excuse, let me emphasize, gave Putin no excuse to blame this on the West or to blame this on NATO," Biden said at a news conference at the White House.

The president added that the incident was "part of a struggle within the Russian system."

The European Union Foreign Affairs Council met Monday and discussed the attempted rebellion by the Wagner paramilitary group over the weekend.

Josep Borrell, the European Union High Representative for Foreign Affairs, told reporters at a news conference after the meeting that "the situation remains complex and unpredictable" and 27 EU states are remaining vigilant.

U.K. Foreign Minister James Cleverly released a statement Monday claiming the "Russian government's lies have been exposed by one of President Putin's own henchmen."

"Prigozhin's rebellion is an unprecedented challenge to President Putin's authority, and it is clear that cracks are emerging in the Russian support for the war," he said.

In the wake of Saturday's short-lived attempted rebellion against the Kremlin by the Wagner private military company, Mikhail Khodorkovsky, an exiled oligarch considered one of Putin’s best-known opponents, told ABC News he supports the mutiny and encourages Russians to back the leader of the mercenary group.

Once Russia’s richest man, Khodorkovsky, a Putin opposition activist, spent 10 years imprisoned after he challenged Putin, his case now considered a foundational moment for Putin’s regime.

When Wagner founder Yevgeny Prigozhin and his fighters marched on Moscow Saturday before making a sudden about-face, Khodorkovsky was notable among Russia’s pro-democracy opposition in calling on people to support Prigozhin, arguing that allowing him to remove Putin would create an opportunity for the democrats.

Khodorkovsky told ABC News he believed Prigozhin’s actions were a real coup attempt and that it had “seriously undermined” Putin’s power. He predicted that similar opportunities to collapse the regime will be launched soon.

"The blow to Putin’s reputation, to the authorities’ reputation, was absolutely fantastical," Khodorkovsky said. "Putin’s government today is, without a doubt, strongly undermined by what happened -- his authority, his ability to control the security services is seriously undermined."

Khodorkovsky said Prigozhin’s march on Moscow had undermined Putin’s popularity, showing neither ordinary Russians nor the security services were prepared to act to protect him.

“Along the entire route of Wagner's columns, no one in any way tried to hinder him (Prigozhin). Even the security forces did not try to stop him," Khodorkovsky said. “It showed that, in fact, inside the country, Putin has an absolute void."

Khodorkovsky said he did not support Prigozhin himself -- considering him a "war criminal" -- but that the democratic opposition should have sought to help him overthrow Putin, and then taken power from him after.

Khodorkovsky criticized other parts of the anti-Kremlin opposition who attacked him for calling on people to assist Prigozhin, saying he believed the opposition had “slept through” the opportunity and suggesting it should have sought to stage a rebellion in Moscow at the same time.

"There will definitely now be more such opportunities because of Putin’s weakening. But the next time we need to simply be more ready," said Khodorkovsky, who is living in exile in England. "If an uprising had started in Moscow to meet Prigozhin then a situation could have developed quite differently.
