This morning on Capitol Hill, Secretary of Health and Human Services Robert F. Kennedy Jr. will appear before the Senate Finance Committee to answer questions.

But unofficially, the hearing will offer the first chance for senators to grill Kennedy since the the CDC's internal war over vaccines spilled into public view, pitting scientists and medical professionals against RFK Jr.'s MAHA loyalists.

Plus, President Donald Trump engages with European leaders on Ukraine and Russia, and a who's who of tech world CEOs descend on DC for a Rose Garden soiree.
