WASHINGTON – United States Trade Representative Katherine Tai today announced the appointment of Katy Mastman as Acting Assistant U.S. Trade Representative for Labor. 
“Katy’s expertise and experience in domestic and international labor policy, from the U.S. Department of Labor to USTR, have been invaluable to our progress in implementing President Biden’s inclusive, worker-centered trade agenda. I look forward to working with Katy in this new capacity as we continue to empower workers and strengthen the middle class,” said Ambassador Katherine Tai.  “As we welcome Katy into this new role, we must say farewell to Josh Kagan. Josh embodies our collective commitment to putting workers first and including their voices and perspectives in our trade policies. Josh’s leadership has been instrumental in our successful use of the USMCA Rapid Response Labor Mechanism and work to eradicate forced labor in supply chains. I want to thank him for his tireless work and dedication at USTR and wish him the best as he embarks on this new chapter.”
