Whistleblower attorney Mark S. Zaid targeted President Donald Trump in a 2017 tweet saying, “We will get rid of him.”

Zaid now serves as an attorney for the whistleblower accusing Trump of demanding that Ukraine assist the United States in an investigation of former Vice President Joe Biden and his son Hunter over the latter’s work for Ukrainian gas company Burisma.

The attorney initially responded to a tweet from the U.S. State Department wishing a happy Canada Day to Canadians on the nation’s 150th anniversary. “Since Jan 20th, I would much rather be in Canada. What a great country! We’ll be great again when @realDonaldTrump leaves,” he tweeted.
