WASHINGTON (AP) — Jill Biden is promoting two of her passions: military families and cancer research. She held separate virtual meetings Wednesday with the spouses of senior defense officials and the staff at the National Cancer Institute. She told the military spouses that she looked forward to using her new platform to help support military families. She also pledged the Biden administration’s commitment to the institute’s cancer research. The Bidens’ son Beau served in the Delaware Army National Guard. He died of brain cancer in 2015 at age 46.
