"delaying an Obama-era rule to prevent disproportionate numbers of minority children from being funneled into special education classes."
Don't you think that maybe these minority children might BENEFIT by being in these special education classes (and probably taught by teachers with specialized knowledge). As far as I know, there are procedural steps that evaluate if classes are needed - if admitted, there are periodic testing and review for eventual dismissal from programs. To deny admittance because of a perceived stigma or having numbers "look" good may be doing minority kids a disservice.
