Most cabinet nominees invite their families and key supporters to attend their confirmation hearing. Yet, Robert F. Kennedy Jr.’s team is calling upon thousands of Americans to descend on the nation’s capitol to rally behind his nomination.

Kennedy, President Donald Trump’s nominee to lead the Department of Health and Human Services (HHS) is set to appear before the Senate Finance and Health, Education, Labor and Pensions committees Wednesday and Thursday flanked by a legion of “Make America Healthy Again (MAHA)” advocates. If busloads of supporters were to pack the Senate Dirksen building hallways as planned, it would be a striking display of grassroots support for one of Trump’s cabinet nominees whose confirmation fate is uncertain due to a number of Senate Republican holdouts.
