On August 10, 2015, the Ninth Circuit Court of Appeals ordered the EPA to respond no later than October 2015 to a petition from pesticide activists requesting a chlorpyrifos ban. The court called the EPA's failure to respond for more than eight years (neither granting nor denying the petition) an "egregious" delay.
So, saying this is all Trumps fault is utter bullshit, yet again. Obama had 8 years to ban the crap and did absolutely nothing. At least you have to give the Trump administration credit for making a decision, rightly or wrongly, something the previous one didn't have the balls to do. Not making a decision when dealing with peoples health is just as egregious as making the wrong one.
