(Reuters) - U.S. Republican presidential candidate Donald Trump said on Monday it was "disgusting" that Pfizer Inc will move its tax base overseas as part a deal to buy Allergan Plc.

"The fact that Pfizer is leaving our country with a tremendous loss of jobs is disgusting," Trump said in a statement. Pfizer has said the $160 billion deal will increase its presence in the United States.
