The president needs to change the law or with the jointer of the House and the Senate enforce the law he swore to execute faithfully. That is required under the constitution. My representatives will never permit the sale of dope.

BTW, did you happen to see President Trump humiliate Jeff Sessions the other day? Did I say humiliate? More like strip him down and mock his small “junk” front of the cabinet, Melania and the entire country.
