Sens. Jacky Rosen (D-Nev.) and Cindy Hyde-Smith (R-Miss.) introduced legislation Thursday that would help small and medium businesses hire and train mid-career professionals in the fields of science, technology, engineering and mathematics (STEM).

The bill would provide $50 million in grants to those employers competing for STEM workers, prioritizing businesses looking to hire women, Black and Latino workers and individuals from rural areas.

The measure would fund "returnships," or midcareer internships, for workers who have either left the STEM workforce, or who want to transition into the field. The grants would require such internships to last at least 10 weeks, with access to mentorship and training.
