Stevie Wonder posted a video on Martin Luther King Jr. Day, voicing his disapproval with lawmakers who are preventing the passing of voting rights legislation, according to HuffPost.

"Any senator who cannot support the protection of voting rights in the United States of America cannot say that they support the Constitution," he said. "Stop the hypocrisy."

Stopping short of dropping a profanity, he added, "Cut the bull-tish," stressing the last syllable.

"If you care and support our rights, do the hard work. You can't please everybody, but you can protect all of us. And to keep it all the way real: The filibuster is not working for democracy. Why won't you?" the musician concluded.

The music icon worked tirelessly with King's widow Coretta Scott King to make her husband's birthday a federal holiday. The duo organized tours and marches in the early 1980s. Eventually, former President Ronald Reagan signed the bill, officially recognizing the day as a federal holiday.

The passage of the voting rights legislation is currently being obstructed by two Democrats, Sen. Joe Manchin (W.Va.) and Kyrsten Sinema (Ariz.), as Democrats discuss wanting to end the filibuster.

"If we miss this time and the state legislative bodies continue to change the law not as to who can vote but who gets to count the vote, count the vote, count the vote — it's about election subversion, not just whether or not people get to vote," Biden said after meeting with Senate Democrats, HuffPost reports.
