The White House attempted to defend the policy of blackballing people who have used marijuana.
"The White House's policy will maintain the absolute highest standards for service in government that the president expects from his administration, while acknowledging the reality that state and local marijuana laws have changed significantly across the country in recent years," an unnamed spokesperson said. "This decision was made following intensive consultation with career security officials and will effectively protect our national security while modernizing policies to ensure that talented and otherwise well-qualified applicants with limited marijuana use will not be barred from serving the American people."
So looks like a security policy decision, which I don't agree with,
However let's see if he backs down from his election stance on the subject. If so, there will be hell to pay as the vast majority of people want legalization. Additionally, it's decriminalization is more than a discontinuation of prohibition, it's a civil rights issue.There is a disproportional amount of black people still being arrested for possession.
I doubt if there were true concerns then Booker and Schumer wouldn't still be pursuing legalization.
