Democratic Rep. Ted Lieu had no problem voicing his opinion of the president on Twitter on Saturday after Donald Trump said that he will be happy when Obamacare “explodes” and fails because then maybe everybody will start listening to him.

According to TheHill.com, after facing a humiliating loss for his health care reform, Trump tweeted “ObamaCare will explode and we will all get together and piece together a great healthcare plan for THE PEOPLE. Do not worry!”

Lieu, who has not been shy about criticizing Trump’s administration and its possible ties to Russia, attacked the President’s indifference toward U.S. citizens.

“‘President’ @realDonaldTrump: You truly are an evil man. Your job is to help Americans. Not intentionally try to destroy their lives,” wrote Lieu.

In a second Tweet that Lieu posted, “Mr. ‘President’: Art II of Constitution requires you to faithfully execute laws passed by Congress. Subverting #Obamacare violates your Oath.”

Lieu has also called on America to “pause the entire Trump agenda” until the investigation into the role Russian officials played into helping Trump win is over.

Lieu’s office released a statement: “Other than allowing routine governmental functions, there must be a total and complete shutdown of any agenda item being pushed by the Trump Administration. Congress cannot continue regular order and must stop voting on any Trump-backed agenda item until the FBI completes its Trump-Russia collusion investigation.”
