Trump Mocks Obama's Healthcare Plan at Colorado Rally, Says 'We Should Impeach' Him

President Donald Trump took another swipe at his predecessor, telling supporters that Barack Obama's healthcare plan warrants him being impeached.

"Impeach Obama. Get him out of office," Trump said during his stump speech in Colorado Springs on Thursday night. "No, nobody thought of that. We caught him in a lie 28 times at least he is on record. Nobody said, 'Let's impeach him.'"

While it is not clear whether Trump meant Obama should have been impeached during his term, or now, there is a legal debate as to whether a former president can face impeachment, a process aimed at removing a politician from office.

Trump told a cheering crowd about his administration's achievements, saying that it was "protecting your social security, your Medicare and is fighting to give you great, great healthcare, already done a good job."

He then took aim at the Affordable Health Care Act, saying, "We are defending your right to keep the doctor and to keep the plan of your choice.

"President Obama, 28 times he said, 'keep your doctor, keep your plan. keep your doctor, keep your plan... Right? " referring to health insurance changes under what is also known as Obamacare.

Trump continued: "It was a lie. We should impeach him. We should impeach him," to cheers at the Broadmoor World Arena.

In December, during a House Judiciary Committee hearing in an apparent reference to Obama, Republican Matt Gaetz said that "maybe it's a different president we should be impeaching."

The legal blog Findlaw.com noted that the U.S. Constitution is unclear on this point. It said that pro-impeachment scholars argue this could stop office holders from resigning before a trial and conviction could occur.

Princeton University professor Keith Whittington said that the Constitution does not restrict impeachment powers to current office holders.

"If impeachments are to protect the republic from dangerous officeholders, then the ability to disqualify a former officer who has been demonstrated to have committed grave abuses of office in the past might be valuable," Whittington wrote on Reason.com.

It was the second Keep America Great Rally during which Trump mentioned Obama.

At his rally in Arizona on Wednesday, in a boast about how median income had risen during his time in office, Trump referred to "Barack Hussein Obama," eliciting jeers from the crowd with one supporter shouting "Lock him up."

Trump has taken issue with Obama recently, especially after the former president marked the 11 years since the American Recovery and Reinvestment Act, with a tweet on Monday, saying the bill was responsible for "more than a decade of economic growth and the longest streak of job creation in American history."

But Trump hit back, tweeting, "Did you hear the latest con job? President Obama is now trying to take credit for the Economic Boom taking place under the Trump Administration."

Trump said that under Obama the U.S. had the "WEAKEST recovery since the Great Depression," adding, "NOW best jobs numbers ever." Trump finished off by saying, "THE BEST IS YET TO COME. KEEP AMERICA GREAT!"
