President Joe Biden has reportedly touched on Vice President Kamala Harris’s running mate prospects, expressing preferences for Govs. Josh Shapiro (D-PA) and Tim Walz (D-MN).

Biden has mostly remained mum on who he favors in the vice presidential sweepstakes, telling reporters on Friday, “I’ll let [Harris] work that out.” He has shown clear favorites behind the scenes, however, with a senior adviser telling CNN that his favorites are Shapiro and Walz.
