Senator Jeanne Shaheen’s staff gathered at a loading dock in the Hart Building basement to receive a special delivery: a U-Haul truck carrying an 8-foot-tall moose named Marty. The event, marked by unloading coolers of food and drinks, underscores the personal traditions that accompany senators departing Washington.

The moose delivery comes amid a wave of Senate departures, raising questions about whether such informal customs will endure. Shaheen, a New Hampshire Democrat, has served since 2009, and her exit is part of a broader turnover that could reshape institutional norms.

According to Roll Call, a dozen staff members participated in the unloading, highlighting the behind-the-scenes efforts that preserve Senate rituals. The moose’s arrival suggests that even as lawmakers leave, their staffs carry forward traditions rooted in state identities.

These traditions, from quirky deliveries to seniority perks, may face pressure as a new generation of senators takes office. Observers note that the erosion of bipartisanship could weaken such practices, which often rely on cross-aisle relationships.

Critics argue that focusing on symbolic gestures like the moose delivery overlooks the substantive policy work senators leave behind. They contend that tradition alone cannot sustain the institution without broader reforms.
