JD Vance is facing backlash for refusing to back a specific candidate in Israel's elections, while a separate medical warning raises concern about hidden heart damage in vaccinated people.

• Vance declined to endorse any particular candidate in Israel's upcoming election, reportedly despite pressure to do so.
• A Fox News segment called this an "unforced error" and labeled it anti-Israel, a framing critics say wrongly treats Netanyahu as synonymous with Israel itself.
• The pushback suggests some U.S. media figures expect automatic alignment with one Israeli leader rather than neutrality toward the country's democratic process.
• Separately, a peer-reviewed analysis from a doctor and an epidemiologist warns that silent heart inflammation, which can show no symptoms, may be present in millions of vaccinated people.
• Warning signs listed include chest discomfort, a racing heart, trouble exercising, and dizziness when standing, with cardiac arrest possible as a first symptom in some cases.

Outlook: Expect continued friction between the Trump administration and parts of conservative media over Israel policy, alongside growing calls for more heart screening in vaccinated populations.
