Trump, on Monday morning, mocked Romney for participating:

Tremendous sincerity, what a guy. Hard to believe, with this kind of political talent, his numbers would “tank” so badly in Utah! https://t.co/KqHsHmSRKo

A day before, Romney had tweeted a photo of his father George, participating in a civil rights march in Detroit in the late '60s.

The George Floyd murder is abhorrent. Peaceful protests underscore the urgency of addressing injustices. But violence drowns the message of the protestors and mocks the principles of justice.

No Americans should fear enmity and harm from those sworn to protect us. The death of George Floyd must not be in vain: Our shock and outrage must grow into collective determination to extinguish forever such racist abuse.
