BEDMINSTER, N.J. (Reuters) - U.S. President Donald Trump said on Thursday he has not given any thought to the possibility of firing special counsel Robert Mueller, who is investigating possible collusion between the Trump campaign and Russia.

Speaking to reporters at his New Jersey golf club, Trump also said he was surprised by the FBI raid last month of his former campaign manager Paul Manafort, adding that it sent a “strong signal.”
