Before Carmen Yulín Cruz challenged Donald Trump in the wake of Hurricane Maria, she took on another larger-than-life politician. San Juan Mayor Carmen Yulín Cruz’s debut on the world stage was unforgettable. “We are dying here,” Cruz said in a Sept. 29, 2017, press conference after Hurricane Maria ravaged Puerto Rico and a slow, inadequate response from the U.S. federal government compounded the disaster. “So I am done being polite.” Cruz, now 55, was bold and defiant. But it was far from the first time. Five years before she found herself standing up to President Donald Trump, Cruz, whose remarkable journey to power is the subject of this week’s episode of Breaking Big, airing at 8:30 p.m. EST Friday on PBS, was challenging another giant — one of Puerto Rico’s most established political bosses — in order to win her current job. |
