From Donald Trump to Rep. Alexandria Ocasio-Cortez, tweeting has become a big part of being an elected official.

Why it matters: Numerous representatives and senators have followed suit, and these are the ones who tweeted the most during the recently completed 116th Congress, according to data pulled by Quorum.

• By the numbers: Republican Rep. Billy Long of Missouri was the most active, with 265.4 average tweets per week from his personal account.
