President Joe Biden has snapped at a reporter at the end of his press conference on Wednesday in Geneva about the results of his meeting with Russian President Vladimir Putin.

According to Fox News, the reporter asked Biden why he was confident Putin would change his previously malign behavior.

Joe Biden answered the reporter by saying that he was not confident Vladimir Putin would change his behavior and then added, "What in the hell, what do you do all the time?"

The president continued to say that what will change Putin's behavior is if the rest of the world reacts to him and diminishes his standing in the world. He further noted that he was not confident of anything and just simply stating a fact.

The reporter who raised the question was CNN's Kaitlan Collins, who has cited Vladimir Putin's past behavior and his denial of alleged involvement in cyber attacks and downplaying human rights abuses during the press conference of the Russian president.

Collins then asked Biden how it makes up a constructive meeting with the Russian president. Biden said if the reporter does not understand that, she is in the wrong business. The president then walked away.

Joe Biden reportedly approached the press on the tarmac and addressed the reporters before boarding Air Force One.

The president then apologized for the harsh way he answered the reporter's question and said he should not have been a "wise guy," National Review reported.

Collins said she was only doing her job and that the president's apology was "completely unnecessary." However, she added that she appreciated what the president did.

Joe Biden and Vladimir Putin Meeting

Joe Biden said that he made it clear in his meeting with Vladimir Putin that the United States will act against Russia if it continues its behavior that harms America's interests, NBC News reported.

The president said it would take time to know whether there will be any significant progress, and he was not confident that he had done anything to change Putin's behavior.

Joe Biden met with Vladimir Putin for just under four hours. Biden said this was slightly shorter than the White House officials expected but plenty of time to cover critical issues.

Joe Biden said he warned Vladimir Putin that the U.S. has significant cyber capabilities if the Russian president ever tries to violate basic norms.

He noted that he gave Putin a list of 16 entities critical to the U.S. infrastructure that should be off-limits. Biden also said that responsible countries need to take action against criminals who do ransomware activities on their territory.

He then asked experts in both countries to work on specific understandings of what's off-limits and follow up on certain cases.

The president also said that human rights will always be on the table, adding that he would continue to call out Russia for human rights violations.

Joe Biden said how could he be the United States president if he does not speak out against the violation of human rights.

Administration officials said the two sides made some progress on a couple of grounds, such as allowing respective ambassadors to return to their overseas post after both were pressured to return home in April.
