Over the course of the 2016 election, Donald Trump’s twitter account became perhaps the most influential tool in the arsenal of a campaign for a candidate who at the time was a celebrity first, and a politician second. Now that President Trump holds the highest office in the nation and is effectively the most powerful man in the world, his reactive, often inflammatory use of Twitter demands a closer look.

To take that look, White House reporter Abby Phillip and I talked to sources about the history, law, and customs that surround presidential communications. The first episode of The Post’s new podcast applies that reporting to answer some critical questions: Can Trump tweet about anything he wants? Can he continue to use Twitter to make policy statements and support businesses? And what does his direct line to the public mean for the office of the American presidency?

One week into the Trump presidency, we’ve already seen him use Twitter much differently than his predecessor. Former President Obama was the only other commander-in-chief to use this social media platform (Twitter was invented in 2006), and his approach included a communications team that carefully vetted and approved each tweet. Trump, who usually tweets himself or dictates tweets to his staff, has already pushed the boundaries of that precedent since taking office.

So now that he’s president, can he do that? Listen below to find out.
