President Donald Trump plans to introduce a rule allowing states to drug test certain workers who receive unemployment insurance, despite repealing a similar rule last year.

Last March, Trump signed a bill eliminating the regulation, but Politico reports that the White House is looking introduce an expanded version, which would allow states to drug test far more people, including those who apply for unemployment insurance.

Republican argued in 2016 that the rule is too narrow, since it only allows drug testing on those whose occupations already require it, such as pilots.

However, the same rule allowing Trump to repeal is regulation, the Congressional Review Act, may prevent him from reissuing it. The law contains a provision that forbids an agency from issuing a rule that is "substantially the same" as one repealed under the CRA without express permission from Congress.

"The Trump administration appears to be [trying to] prove that not only can agencies issue new rules when past rules have been overturned by the CRA, but that those rules can be even stronger," Amit Narang, a regulatory expert with Public Citizen, told Politico.

"Our perspective all along is this is possible," Lisa Gilbert, Public Citizen vice president of legislative affairs, told The Hill in January.

"People shouldn’t treat the CRA like a scorched earth, ‘we can never regulate again in this space’ dictate."
