Counting that way, 100 percent of the Senate is now using Twitter.
At least three freshman Democratic senators — Sens. Tammy Baldwin (Wis.), Martin Heinrich (N.M.) and Heidi Heitkamp (N.D.) — have yet to set up a new Twitter account to suit their new office, but still have a campaign presence with varying degrees of activity.
Blunt also welcomed several new Republican senators to Twitter in a second tweet on Thursday.
The House and Senate leadership have stepped up to promote the accounts of new members. Creating official Twitter accounts for use by their congressional office has become one of the many necessary steps new members take during their first few weeks after taking office.
