Now, Rochy, try to concentrate:

Firstly, Trump never claimed that Obama banned Iranian refugees, it was IRAQI refugees that Trump accused Obama of banning for 6 months.

But even that claim was wrong:

From Friday 's Toronto Star (among multiple other sources):

"In fact: Trump is wrong that Obama “banned” Iraqi refugees. After two Iraqi refugees were arrested on terrorism charges, Obama increased scrutiny of new refugee applicants, slowing down the process significantly, but did not ban Iraqis entirely or ban all new refugees. Iraqi refugees were admitted to the U.S. in every month of 2011, government figures show, and 9,388 were admitted in total in 2011."
