A group of 145 organizations have released a letter calling on Joe Biden to ban fossil fuel interests from his campaign and administration. The letter reads, “Nearly half of Americans now breathe polluted air, the vast majority of which comes from burning fossil fuels. … To advance environmental justice, you must stand up to fossil fuel CEOs, stop the expansion of oil, gas and coal production, and rapidly transition us away from fossil fuels.” During his speech in Pennsylvania Monday, Biden said he will not ban fracking.
