Trump Deleted Tweets About Luther Strange. Is He Allowed to Do That?

Following Roy Moore's victory in the Alabama Republican Senate primary on Tuesday, President Trump deleted tweets from his personal account about Sen. Luther Strange, whom he had endorsed in the primary.

The tweets, which were archived by ProPublica, urged Alabamans to "finish the job" and "vote today for Big Luther." Trump also deleted an inaccurate tweet telling Moore to win in November; the general election is in December.
