It was only a temporary ban:
"Donald Trump called Monday for a "total and complete shutdown" of the entry of Muslims to the United States "until our country's representatives can figure out what is going on."
In a statement released by his campaign Monday afternoon, Trump included recent poll findings that he says show that a sizable segment of the Muslim population has "great hatred towards Americans."
"Without looking at the various polling data, it is obvious to anybody the hatred is beyond comprehension," Trump is quoted as saying in the statement. "Where this hatred comes from and why we will have to determine. Until we are able to determine and understand this problem and the dangerous threat it poses, our country cannot be the victims of horrendous attacks by people that believe only in Jihad, and have no sense of reason or respect for human life."
