For months now, voting rights advocates have expressed concern over possible voter suppression at the polls on Election Day. This is the first presidential election since the Supreme Court’s decision in Shelby County v. Holder, the 2013 ruling that gutted the sections of the 1965 Voting Rights Act that had given the Justice Department the power to monitor election law in areas with histories of voting discrimination. Following the 2013 decision, Supreme Court Justice Ruth Bader Ginsburg warned that without these VRA protections, discrimination at the polls, particularly against minorities, was likely to increase. “Just as buildings in California have a greater need to be earthquake­ proofed,“ she wrote in her dissent, “places where there is greater racial polarization in voting have a greater need for prophylactic measures to prevent purposeful race discrimination.”

In recent months, concerns over potential voter suppression have proved to be prescient. A report published last week by The Leadership Conference Education Fund found that counties once covered by the VRA’s Section 5—one of the rules diluted by the Supreme Court—have closed at least 868 polling places in advance of the 2016 election. In addition, 14 states will be operating under new voting restrictions this election, including voter ID requirements, while the Justice Department’s capacity to monitor the implementation of those laws is weakened. Another consequence of the Shelby County decision was the DOJ announcement in July that the department had to slash the number of election monitors it would send to the polls, from more than 780 observers in 23 states in 2012 to just a handful of observers in five states. On Monday, the department announced that instead it would deploy more than 500 election monitors to 67 jurisdictions in 28 states.

Donald Trump has often asserted that the election will be “rigged” against him. On his website, he has encouraged his supporters to sign up to be a “Trump election observer” and monitor polling stations for what he says will be voter fraud. In response, state Democratic parties have filed voter intimidation lawsuits against the Trump campaign in six states—Arizona, Pennsylvania, Nevada, Ohio, Michigan, and New Jersey. So far, the Ohio case is the only one where a federal judge issued a restraining order against the Trump campaign compelling them not to intimidate or harass voters at the polls, and that did not last long: This week, a panel of judges from the 6th Circuit Court of Appeals overturned the Ohio judge’s restraining order, and on Monday the Supreme Court upheld that decision.

But allegations of voter intimidation, improper voter ID practices, long lines, and even guns at the polls have been rolling in since the start of early voting across the country—in some states it begins as early as late September. We have collected some reports of problems and will continue to update this post until the last polls close on Election Day.

Earlier, he sent a tweet showing him following a pastor’s bus transporting voters to the polls. (Providing transportation to polls is legal.)
