The White House is shrugging off ethics concerns over President Donald Trump dining with the biggest investors in his meme coin, an exclusive group that includes foreign nationals who typically have restricted access to the president and political process.

Trump is the special guest for a black-tie optional dinner expected to be attended by 220 investors in his $TRUMP meme coin. These investors have collectively spent $400 million on the coin, a type of cryptocurrency that depends on hype to increase its value. The event, which is being held at his D.C.-area golf club on Thursday, is being promoted as “the most exclusive invitation in the world” after a competition among those willing to spend big on Trump’s coin.
