CATONSVILLE, Md. (Reuters) - U.S. President Barack Obama visited a U.S. mosque on Wednesday and declared that attacks on Islam were an attack on all faiths in a move to counter rhetoric from Donald Trump and other Republican presidential candidates that have alienated Muslims.

We have to understand that an attack on one faith is an attack on all our faiths," Obama said at a mosque outside Baltimore. "When any religious group is targeted we all have a responsibility to speak up."
