President Bident traveled to Minnesota on Sunday to deliver remarks at former Vice President Walter Mondale's memorial service.

Mondale died in April 2021 at 93. Biden wanted to attend because he had "an important personal relationship" with Mondale, according to White House Press Secretary Jen Psaki. The service was delayed due to COVID-19.
