WATCH: Beto Explains Why He Was Surprised His Friend Tim Walz Was Picked for VP

During a recent appearance on Jen Psaki's MSNBC show, Democrat Beto O'Rourke said he was surprised that Tim Walz was Kamala Harris's running mate choice. 

When Kamala Harris first took over the Democratic ticket, many different names were thrown around as potential running mates. But after making multiple well-received media appearances, Tim Walz emerged as one of the main contenders. And the Minnesota Governor has been lauded by both voters and the media for his affable manner. 

O'Rourke, who says that Walz was one of his first friends in Congress, told Psaki:

"I was actually really surprised that he was in contention to be nominated for vice president of the United States and surprised that he got picked, only because it is so rare that someone who is so genuinely kind and nice and isn’t a blowhard and a grandstander and a self-promoter ever reaches these levels of political attainment in this country."

The former Texas congressman continued, "He’s just that rare person, who’s just truly a good guy, who’s gotten ahead by getting the job done."

O'Rourke then lauded the job that Walz has done as the Governor of Minnesota, saying, "As governor of Minnesota, he’s made sure that kids can learn on a full belly. That we decriminalize marijuana … we’re not putting people behind bars for something that’s legal in most of the rest of the country."
