Senator Ruben Gallego continues to fulfill his duties as Arizona’s junior senator with no verified developments indicating an imminent departure before the end of May. An April ethics complaint referral tied to his past association with former representative Eric Swalwell has not produced committee findings, Senate action, or public pressure sufficient to force resignation or expulsion. Gallego remains actively engaged in legislative priorities, including recent committee advancement of cryptocurrency regulation measures. Traders assign a 98 percent probability he will stay in office through the deadline because Senate terms run until 2031 and removal requires either voluntary resignation, death, or a supermajority expulsion vote that faces high procedural hurdles. Only a sudden health crisis or explosive new evidence from the ethics process could realistically alter that outlook within the narrow window.
