WATCH: Kamala Harris goes off on GOP chair for pushing Hunter Biden subpoena instead of conducting COVID-19 oversight

Senator Kamala Harris (D-CA) on Wednesday blasted Senator Ron Johnson (R-WI), the chair of the Senate Homeland Security and Governmental Affairs Committee, for holding a vote to subpoena documents related to Hunter Biden amid the coronavirus pandemic.

"Today's agenda reveals a lot about the Senate majority's priorities, sadly," Harris said during a committee hearing. "There are literally matters of life and death waiting for our committee's attention. But instead, this committee is doing the president's personal bidding."

The committee later voted along partisan lines to authorize Johnson to subpoena Blue Star Strategies, a public relations firm that represented Burisma Holdings, the Ukrainian natural gas company where Hunter Biden served on the board.
