This move does not come about as surprising, since apart from all 100 Senators being on Twitter, it is estimated that roughly 90% of the members of the US House of Representatives also own an active Twitter account, totaling 398 members in total. Rewind the clock back by a couple of years to 2011, and approximately 44% of the Senate and 38% of the House had active Twitter accounts, now how about that? In fact, First Lady Michelle Obama sent her inaugural tweet this past Monday, and she already has garnered 124,000 followers in such a short time.
