Wisconsin, Arizona certify Biden's victory in presidential election

Arizona and Wisconsin, two battleground states in the 2020 U.S. presidential election, have officially certified their results, confirming President-elect Joe Biden's victory over incumbent President Donald Trump on Monday.

Arizona's certification was signed by the state's Secretary of State Katie Hobbs, who was accompanied by Republican governor and attorney general, Doug Ducey and Mark Brnovich, and state Supreme Court Chief Justice Robert Brutinel.

Wisconsin Governor Tony Evers also certified Biden as the winner of the state.

"Today I carried out my duty to certify the November 3 election, and as required by state and federal law, I've signed the Certificate of Ascertainment for the slate of electors for President-elect Joe Biden and Vice President-elect Kamala Harris," Evers said in a statement.
