To the Editor:
We the undersigned, founders and leaders of biotech companies, write to express our deep concern and opposition to the executive order signed by President Donald Trump on January 27, 2017, barring the entry of citizens from seven countries into the United States1.
The United States is the world’s greatest developer of medicines and new inventions to ameliorate and cure intractable diseases, a status achieved through massive investment in private and public companies, academia and R&D. Most importantly, our success has been founded on the creativity and dedication of our most precious resource—our people.
