The Senate is due to vote on whether to begin debate on the John Lewis Voting Rights Advancement Act, which would restore state voting requirements to prohibit racial discrimination that were struck down by the U.S. Supreme Court in 2013.

Democrats have made election reform a priority in light of Republican state balloting restrictions passed in response to former President Donald Trump's false claims of massive voter fraud in the 2020 election. At least 19 states have passed laws making it harder to vote, according to the nonpartisan Brennan Center for Justice.

Democrats and voting rights advocates have said the laws will make it harder for Black and Hispanic voters - important Democratic Party voting blocs - to cast ballots.
