And tonight, seven Republican incumbents will be fighting to keep their seats against candidates that Trump backed over them.

It will be one of several tests of the president's power this primary season.

Times political correspondent Shane Goldmacher has more on what races to watch this primary season on today's episode of The Daily.

And The Times will have coverage of the Indiana results as they come in tonight.

In Washington.

Health Secretary Robert F. Kennedy Jr.

announced a plan yesterday to rein in what he's called Americans' overuse of antidepressants.

Kennedy has narrowed in specifically on SSRIs, the most widely prescribed class of antidepressants.

That includes household names like Zoloft, Paxil, Prozac.

The user base is huge.

Roughly one in six Americans reported taking an SSRI this year.

Kennedy acknowledged that patients can benefit from them, and he stressed that he wasn't telling anyone to just stop.

But he argued that too many people start taking the meds without knowing how long they'll stay on them, and with no plan to come off.

He has singled out SSRIs before.

He's previously claimed, without evidence, that they are partly responsible for the rise in school shootings and that they can be harder to quit than heroin, something he repeated yesterday.

For his new effort, Kennedy announced several initiatives, like trainings and new guidelines to nudge clinicians to help patients get off medications and consider other treatment options, like therapy or exercise.

No major medical organizations were represented at yesterday's event.

And my colleague Ellen Barry, who covers mental health, has been speaking with psychiatrists and other experts in the field about Kennedy's new push.

Health authorities are continuing to look into a possible hantavirus outbreak on a cruise ship in the Atlantic Ocean.

Three passengers have died after showing symptoms of the rare disease, and three others are sick.
