How do you explain to your kid why one of his hero’s #BélaFleck cancelled his #Kennedycenter performances? We don’t do art for the money, or for political gain. The focus should be on the music. Thank you Béla for doing the right thing and being a role model for the next generation. #music #art

My thoughts on ABC news- Scientists, not political appointees, should be who advises the public on clinical guidance. RFK needs to meet with CDC career leaders and learn about the agency's responses to outbreaks and overall programs vs directing CDC website changes based on ideology not science
abcnews.go.com
Video Former CDC chief on agency webpage saying autism, vaccines link ignored
Dr. Debra Houry, who resigned from her position as chief medical officer of the CDC in 2025, called the change on the CDC’s website "disturbing."

Dear Senators:
Earlier this month, the Trump administration confirmed ordering NIH and HHS to eliminate 35% of all contracts', amounting to a $2.6 billion cut to NIH?. We write to inform you that these cuts will damage vital clinical care and medical research, conducted at NIH and funded by NIH at centers across the country. Despite what the Trump administration's political employees claim, there is no way to implement these cuts without damaging the NIH mission to understand biology and to understand, prevent, and treat disease and improve human health.
All Americans are touched by diseases like stroke, cancer, and Alzheimer's that NIH works to prevent and cure. NIH has been a worldwide beacon and powerful leader in this research. Currently, this work is under attack from the Trump administration, notably but
