An EC tie has occurred. A House and Senate deadlock in addition seems unlikely and doesn't seem likely to need extra wording. But may as well deal with third candidate causing no one to get majority as well as tie possibility.
So change to
"Donald J Trump (POTUS 2016-2020) will be President on Feb 1, 2021 having been awarded a majority of the US electoral college or elected by the House of Representatives in the event of no candidate getting a majority of the electoral college."
