An artist projected “Pay Trump bribes here” and “emoluments welcome” onto the facade of the Trump Hotel in Washington, D.C, on Monday night, in protest of President Donald Trump’s failure to divest himself from his business empire.

The artist, Robin Bell, also projected the entire text of the Emoluments Clause of the Constitution.

Foreign leaders can literally pay to stay at the president’s property, mere steps from the White House, Bell pointed out to CNN in an interview. This appears to violate the Emoluments Clause, which forbids officials from accepting money and gifts from foreign governments.

“It’s a pretty clear cut example of impropriety,” Bell told CNN. “This is not like politics as usual. The rules and the lines are being pushed so far and this seemed to be so clear to me.”

In January, watchdog group Citizens for Responsibility and Ethics in Washington sued the president over his business ties, alleging that his businesses accept money and favors from foreign politicians and governments in violation of the Emoluments Clause.
