It's a record that may never be broken—not by another president, at least. President Trump broke his own record for most presidential tweets in a month in September, when he tweeted or retweeted 790 times, CNN reports. He set the previous record in May with 695 tweets. He also set the record for most tweets from a president in a week, with 240 the week of Sept. 23. USA Today notes that Trump's tweeting intensified after news of the Ukraine whistleblower surfaced and Democrats started calling for his impeachment. In tweets since Sept. 19, he has used the words "Ukraine" or "Ukrainian" 56 times, "whistleblower" 25 times, "treason" five times, and mentioned Joe or Hunter Biden 24 times.
