Former Nalcor CEO Ed Martin broke his silence Tuesday to fire back at Premier Dwight Ball over the Muskrat Falls project. Martin says he never saw an assessment conducted by SNC-Lavalin in 2013 that warned of serious risks. But the premier was still raising questions about what Martin knew. SNC-Lavalin says it attempted to hand the report to Nalcor, but would not answer whether it was specifically given to Martin.
