As someone who has lived my entire life in Washington, DC, the conversion of the historic Old Post Office on Pennsylvania Avenue into a Trump International Hotel is outrageous. It encapsulates the current POTUS's ignorance of how to conduct himself in the office to which he has been elected, and his disregard for laws, traditions, or any other normal constraints upon an individual conducting government business. Instead, it flaunts the exploitation of the Presidency for private gain, a clear violation of the Constitution, and does this only blocks from the White House.
The building is portrayed in this drawing as the refuge of an impeached, but unrepentant Trump, with Putin's limo, a tank, and armed guards. Guards were briefly posted in reality when the building was vandalized before the inauguration, which prompted this imagining of a possible future.
