Just like "Russiagate" and the Mueller investigation, and a number of other attempts to overturn the 2016 election.
We've had three years of accusations and investigations with untold millions of dollars spent in a never-ending Democratic Party effort to remove President Trump from office.
Why do the Democrats keep swinging and missing at Trump? They can't make a good case for abuse of power because they don't really oppose Trump's most egregious abuses of power. Congress, with a few exceptions, strongly supports the President flouting the Constitution when it comes to overseas aggression and shoveling more money into the military-industrial complex.
In April, 2018, President Trump fired 100 Tomahawk missiles into Syria allegedly as punishment for a Syrian government chemical attack in Douma. Though the US was not under imminent threat of attack from Syria, Trump didn't wait for a Congressional declaration of war on Syria or even an authorization for a missile strike. In fact, he didn't even wait for an investigation of the event to find out what actually happened! He just decided to send a hundred missiles – at a cost of hundreds of millions of dollars – into Syria.
