Chelsea Clinton is after all a reliable critic of the administration.
The problem is she here is not criticizing the Trump administration, but the Obama one.
As reported by Twitchy, had she clicked on the link before she tweeted in response to it, she would have realized it.
The link goes to Statnews, which reported that
During the last two years of the Obama administration, staff at the Environmental Protection Agency assured Bryant and local officials in other communities nationwide that they would soon issue new, more stringent guidelines for assessing the risk of lead contamination in soil. Those guidelines were expected by many to lower the threshold deemed dangerous for children and compel owners of contaminated properties to fund cleanup efforts. The effort was aimed at cutting the allowable level of lead at some of the nation’s most contaminated waste sites in half.
However
But in the final days of the Obama administration, the EPA instead issued an internal memo — obtained by STAT — that sidestepped the issue of a specific new threshold for acceptable lead levels. The agency provided only general guidance on the factors that should be used when determining whether cleanups are required. It did not, however, lower the threshold for soil cleanup to one that would translate into a blood level of 5 micrograms per deciliter, down from the current level of 10, as was expected.
So either Chelsea deliberately went after the Obama administration for ‘sidestepping decision to tighten standards for lead levels,’ doubtful for a budding Democratic politician. Or Chelsea thought she was attacking Trump and snared poor Obama instead.
