Tulsi Gabbard of Hawaii has doubled down on her calls for popular Monsanto product Roundup to be banned after a federal jury dealt a major blow to the agrochemical giant, asserting that Roundup played a substantial role in causing a California man's cancer. 'I’ve said it before, I’ll keep saying it: ban roundup!' Gabbard said in a tweet on Friday. 'It’s long past time we stopped relying on corrupt corporations with a profit incentive to fund science telling us their chemicals are 'safe.' Victims shouldn’t have to go to trial to get the truth.'
