President Trump’s boastful tweet early Saturday that his Aberdeen, Scotland-area golf course might be “the greatest” anywhere worldwide spurred criticism that he was using the office for financial gain, The Washington Post reports. “Very proud of perhaps the greatest golf course anywhere in the world. Also, furthers U.K. relationship!” Trump tweeted at 5:31 a.m. Citizens for Responsibility and Ethics in Washington, which is suing Trump on the basis that the U.S. Constitution bars national leaders from using their office for financial gain, voiced its criticism shortly thereafter. “There it is. The president is using an official statement as an ad for his business and making sure everyone knows he ties his business to US relationships with foreign countries,” the group tweeted just seven minutes later.
