Michigan electors will receive a police escort if they vote for Joe Biden as next president on Monday, US media reports.
Members of Stop the Steal, an activist movement to keep Donald Trump in power despite his defeat, say they will protest in front of the Michigan Capitol.
Inside the building, 16 electors will sign certificates stating their support for Joe Biden as president and Kamala Harris as vice president.
The electors are reportedly given extra protection when they drive their cars to the Capitol in the capital, Lansing. As far as is known, it is the first time in the history of the state that extra security has been used for the ballot.
Biden won Michigan by more than 154,000 votes, but dozens of armed Stop, the Steal protesters, went to the home of Secretary of State Jocelyn Benson last Saturday and shouted swear words until police arrived.
The 538 electors in the United States will vote for one of the two presidential candidates on Monday. They do this in their own state, the vote then goes to the capital Washington. The results of the elections will then be officially determined on 6 January.
In the US, citizens’ votes do not go directly to a presidential candidate, but to the electors. The electors are awarded by state on a winner-takes-all principle. The candidate who wins a state, therefore, gets all the electors for that state, even if the difference in votes was minimal.
Democratic challenger and president-to-be Joe Biden has received 306 electors, and President Donald Trump is at 232.
