The anti-Trump Utah congressman was spotted at a protest march in Washington DC on Sunday. Romney later tweeted a protest selfie with the caption “Black Lives Matter.”

An aide to the senator told the Washington Post Romney wasn’t intending to “publicize” his participation in the protest, having “spontaneously” joined the march after coming across a group of 1,000 to 1,500 evangelicals demonstrating near the Capitol. Romney told the outlet he was participating in the demonstration “to make sure that people understand that black lives matter.”

The failed 2012 presidential candidate has tweeted repeatedly in support of the protests that began on Memorial Day following the police killing of George Floyd in Minneapolis, diverging from the Republican rank and file, who have largely backed President Donald Trump’s calls for “law and order” and support for the police.

However, many on social media saw Romney’s participation in the march as a transparent publicity stunt, noting the politician’s history of backing the same racist policies that created the circumstances of Floyd’s death.
