Lawyers for Mr Trump have argued that the cannot be tried in the US Senate as he is now a private citizen.
But apparently Mr Trump did not believe that same standard applied to his predecessor while he himself was in the White House.
The ex-president told the crowd in Manchester, New Hampshire, that Mr Obama should be impeached for his promises on healthcare.
“Remember President Obama, you can keep your plan, you can keep – 28 times – you can keep your doctor,” said Mr Trump at the February 2020 rally.
“That didn't turn out very good. We should impeach him for that.
“Why aren't we impeaching him? 28 times, you can keep your doctor. We should impeach President Obama,” Trump declared to the crowd.
