The Senate voted Tuesday to roll back an Obama-era regulation that limits who can be drug tested while applying for unemployment benefits.

Senators voted along party lines 51-48 under the Congressional Review Act to cut the rule. The legislation already passed the House and now heads to President Trump's desk, where he is expected to sign it.

Under a 2012 law, states can only drug test individuals applying for unemployment benefits if they were previously fired for drug use or work in jobs for which workers are regularly drug tested. The Obama rule specified a list of jobs the could be included under the law.

Republicans have argued the Obama regulation amounted to a federal overreach that limited a state's ability to determine its own drug testing policy.

He added that the Labor Department "should go back to the drawing board."

The Trump administration has also voiced support for getting rid of the rule, arguing its definition of occupations is too narrow and limits a states ability to drug test.

But Democrats warn that by nixing the rule lawmakers will be allowing states the ability to randomly drug test workers who through no fault of their own are unemployed, poor or in need of public assistance.

Republicans are using the Congressional Review Act to take a hammer to Obama-era rules. The law allows Congress to overturn some regulations with only a simple majority.
