President Donald Trump on Wednesday vowed to fight a possible impeachment effort by Congressional Democrats in the US Supreme Court.
However, the US constitution, and the court itself, have made clear that it has no role in impeachment proceedings, which represent the legislature's power to check wrongdoing by the president.
But Trump's tweet suggested the White House is taking seriously a debate among Democrats on whether to launch the process that could remove the president on the basis of
evidence of obstruction of justice in the Mueller report released last week.
The report has shown reluctance on concluding if the findings amounted to a crime. It has left the decision to Congress where the House of Representatives has the power to impeach a president.
Democrats in US have been debating whether undertaking a politically divisive impeachment effort would be a good idea less than 19 months before the next presidential election.
