Minnesota Gov. Tim Walz joked about his “interesting” first week as Kamala Harris’ running mate on the Democratic presidential ticket and criticized Donald Trump’s background on Wednesday during a Denver fundraiser that collected $3 million for the campaign. “This week has been interesting,” Walz told roughly 150 attendees in the backyard of the 33,000-square-foot Phipps Mansion, owned by Democratic megadonor Tim Gill.
