Executive actions are far more ephemeral and easily discarded than legislation, which can set up a whipsaw effect, as each president scrambles to undo the work of his predecessor. Just as Mr. Trump set about reversing as many of President Barack Obama's directives as possible, Mr. Biden is now working to reverse many of Mr. Trump's reversals. With executive orders, there is always another presidential election just a few years off, threatening to upend everything.

Notice anything about that paragraph from the NYT?

Notice how they refer to President Trump as 'Mr. Trump' and Biden as 'Mr. Biden'? Who do they refer to as President?
