Can Trump serve a third term as US president?

Donald Trump has not ruled out the possibility of a third presidential term, saying he would "love to do it".

Already, the Trump Organization is selling red caps that simply read "Trump 2028", seeming to promote the president as a candidate in the election.

By that time, though, Donald Trump will have served two terms in the White House, the limit set by the US Constitution.

The release of the $50 cap (£38) earlier this year followed Trump's comments that he is "not joking" about wanting to serve a third term.

The US Constitution says that "no person... shall be elected more than twice", but some Trump supporters - and the president - have suggested there could be ways around that.
