Tammy Duckworth makes history as first sitting senator to give birth in office and first woman to bring a baby to the senate floor in 229 years

One day after the United States Senate voted to allow babies onto the chamber's floor, Sen. Tammy Duckworth made history by bringing her 10-day old newborn with her to vote.  

 Duckworth thought she might be the deciding vote in stopping a disputed Trump administration nominee. That turned out not to be the case, but the baby, Maile Pearl Bowlsbey, still caused a stir on the floor as the first one to appear with a mother who was a senator.

On April 9, Duckworth became the first senator to give birth while in office.  

The Senate chamber became one of the most exclusive clubs in the 1800s, when senators complained about too many people who were allowed to come onto the floor. Senators then created a list that has been added to over the last century but still allows just a few people into the chamber. Those include the president and vice president, members of Congress, the mayor of Washington and senators’ staff members. And, now, newborn babies are part of that list.
