‘Going to get worse’: Joe Biden mocked following another speech gaffe

US President Joe Biden hosted a dinner for NATO leaders where he made another gaffe during an address on Wednesday night.

Social media users mocked the oldest-ever sitting president ahead of his “big boy” press conference on Thursday.

“It’s not going to get better, it’s going to get worse,” wrote one user.

Upon the arrival of NATO leaders, President Biden and his wife, First Lady Jill Biden, greeted them.

The White House dinner event celebrated 75 years of NATO, where Biden toasted the members’ shared ties and alliances.

“75 years ago, when our nations created NATO, former President Truman said, and I quote, ‘What we’re about to do here is a neighbourly act,’" Biden said.
