Longtime Never-Trumper Mitt Romney tweeted “Black Lives Matter“ on Sunday after marching alongside nearly 1,000 Christian activists to the White House to protest racial injustice. The demonstration across the city’s highways, organized by pastors, is intended to recall the Civil Rights era Selma-to-Montgomery marches in 1965. The Republican senator from Utah said he is marching “to make sure that people understand that Black Lives Matter.” Romney has said he will not vote to re-elect President Donald Trump in November. The march is part of a worldwide movement following George Floyd’s death in police custody on May 25.

The march began in Washington, D.C.’s Ward 7, the easternmost governing segment of the District and a predominantly black region of the city. Community members have voiced concerns about police conduct in the area in recent years.
