President Donald Trump reportedly will announce Friday whether he's going to de-certify the Iran nuclear deal.  CBS News reports Trump will announce his decision in a speech Friday.  For more than 2 years, Trump has criticized the deal between Iran, the U.S. and 5 other world powers.  It calls for Iran to stop its nuclear development program, in exchange for relief from crippling economic sanctions. 

 If Trump decides to de-certify the deal, Congress will then have to decide whether to impose sanctions again.
