Trump presidency expected to be certified by US electoral college
Millions of Americans who consider Mr Trump unfit to occupy the Oval Office have signed an online petition calling for Republican electors not to vote as directed by their state's popular ballot.
Some have posted electors copies of founding father Alexander Hamilton's writings in his Federalist Papers, which state that the meeting of the electoral college "affords a moral certainty, that the office of President will never fall to the lot of any man who is not in an eminent degree endowed with the requisite qualifications".
A handful of Democratic electors are making a longshot bid to persuade their Republican counterparts to vote against Mr Trump.
These Democrats are so desperate to stop Mr Trump that they have even offered to vote against Hillary Clinton and unite with the other electors behind a consensus Republican candidate.
