Commerce Secretary Penny Pritzker made a brief visit to Fresno on Wednesday, where she talked with farmers and agriculture officials about trade, economic opportunities and, primarily, water. “She was well briefed,” said Rep. Jim Costa, the Fresno Democrat who invited Pritzker to visit. “She knew the challenges created for water users here in the Valley.” Costa said Pritzker talked for 30 to 40 minutes about efforts by the U.S. Department of Commerce to improve economic activity for businesses, as well as business opportunities and the impact of trade for California.
