Documents reveal that Environmental Protection Agency chief Gina McCarthy may not have told lawmakers the truth when she said new climate rules were published in a timely manner.

The EPA published its so-called New Source Performance Standard (NSPS) for power plants in early January, more than two months after it was submitted to the Federal Register. Furthermore, the EPA announced the standard, which would effectively ban coal-fired power plants, in late September.

Republicans have alleged that the delay in publishing NSPS was politically motivated, arguing that the Obama administration’s actions will push the finalizing of the costly rule until after the elections this fall.
