Reps. John Lewis and Bennie Thompson will not be attending the opening of the Mississippi Civil Rights Museum this weekend in protest of President Trump's attendance.

The two lawmakers said in a statement: "President Trump's attendance and his hurtful policies are an insult to the people portrayed in this civil rights museum... After President Trump departs, we encourage all Mississippians and Americans to visit this historic civil rights museum."

Why it matters: Lewis was a key leader and icon of the Civil Rights movement, and has been criticized by President Trump in the past for being "all talk...no action."
