During a press conference on Sunday, President Joe Biden's staff hurried to cut him off as he began to go off on a rambling answer to a reporter's question.

The White House staffers seemed to be trying to prevent him from answering further questions, as The Daily Caller reported.

A journalist approached the president while he was giving a speech in Vietnam and asked him whether he is concerned about the stability of the relationship between the United States and China due to the absence of official talks between himself and President Xi Jin Ping.

A follow-up question was posed, referencing the G20 declaration (which did not mention Russia by name as an aggressor), about whether the issue of the invasion was becoming a wedge between states or if the United States' commitment to Ukraine would change. The declaration did not name Russia expressly as an aggressor.

Biden stated that it was not a "wedge issue with the global south" but rather an issue with "Russia."

“I’ll tell you what, I don’t know about you, but I’m gonna go to bed,” Biden said randomly while trying to answer the first half of the question about China.

A reporter then asked a question that was not audible off-screen.

“We talked about; we talked about it at the conference overall, we talked about stability, we talked about making sure that third world, excuse me, third world, the, uh, the, uh, the southern hemisphere had access to change had access to — had access to, it wasn’t confrontational at all, we— ”

“Thank you, everybody, this ends the press conference,” a Biden aide could just be heard saying over the loudspeaker as the president of the United States continued to mumble before saying “thank you” and walking off the stage.

A reporter was heard asking President Biden about his dedication to defending human rights. In response, Biden was heard saying, in part, that he had brought up concerns about human rights "with every person I met with."

An other reporter was heard shouting a question about his son, Hunter Biden, who is still the subject of an inquiry.

On Sunday, Biden traveled to Hanoi, Vietnam, to meet with Vietnamese officials and explore ways that the two countries might work together to battle climate change and deepen their connections.

The president's recent seeming confusion is the latest in a long line of what some consider concerning activity from the nation's oldest president, who appears to be showing signs of mental decline.
