"Happy 74th birthday to the fabulous Dr. Jill Biden! It's hard to believe that just yesterday she was a spunky young 73-year-old. Cheers to another year of grace, wisdom, and rockin' those chic outfits. May you continue to inspire and uplift those around you with your grace and charm. Keep making Dr. Biden proud, and here's to many more years of being the coolest 74-year-old around. Happy birthday, Jill!"
