Sen. Heidi Heitkamp had a late night and little sleep on her birthday, but she wasn’t out on the town celebrating.  

As the Senate reconvened at midnight on Oct.30, and returned to vote on the budget deal, Heitkamp turned 60 years old. After the 1 a.m. vote, the North Dakota Democrat only had a few hours rest before she had to be at the airport for a 6:15 a.m. flight. Heitkamp is traveling with the top senators from the Homeland Security and Governmental Affairs Committee and two House members this weekend to learn about the root causes of migration from the Central American countries of Guatemala and Honduras. And though her birthday began with a Senate vote and continued with more Senate business, she did have a moment to celebrate on the plane when flight crew passed out cupcakes to mark the occasion.  

Heitkamp’s staff also brought a smile to the senator’s face, posting signs in the windows of her Hart office that were visible from the office building’s foyer.  

“Smile! Senator Heitkamp is 60!” read the signs that spanned the office windows.  

A staffer for Sen. Elizabeth Warren, D-Mass., captured Heitkamp’s reaction when she her staff’s show of support Thursday.
