Biden, 81, showed his support for Ukraine by sporting a pin showing the US and Ukrainian flags side by side.
The Democrat was given a standing ovation by the hosts and audience of the ABC talk show on Wednesday.
But many viewers were angered by Biden's pin choice, accusing the president of putting foreign interests above those of America.
The right-wing outlet Townhall.com noted the pin on X, writing: 'Joe Biden is sporting a Ukraine flag pin on "The View."'
