Prime Minister Justin Trudeau highlighted Canada's close relationship with its global allies Wednesday during bilateral meetings at the NATO summit, ahead of a dinner the U.S. president was expected to host at the White House.

Concerns over Joe Biden's health and the possibility of a second Donald Trump presidency have already cast a shadow over the three-day leaders' summit in Washington, D.C. 

Trudeau wouldn't respond Tuesday when a reporter asked him if he had concerns about Biden's age or mental acuity.

But President of Poland Andrzej Duda brushed aside questions about the American president on Wednesday, saying he met with Biden "and there is no doubt that everything is OK."

"We don't need to interfere in the American election," Duda said at the summit.

Eighty-one-year-old Biden's age and mental acuity are under international scrutiny after a disastrous debate performance last month against Trump. 

Biden delivered a clear and forceful speech at NATO's 75th anniversary celebration Tuesday evening at a critical time for the Democratic leader and for stability in his party. With the eyes of the world watching, it was an important moment for Biden to prove he was capable of being in charge.
