McCain's was one of the first responses from national lawmakers after Brewer said she had vetoed the bill.
A wide range of national Republicans had urged Brewer to block the legislation, SB 1062, which would have allowed business owners to refuse to service LGBT customers if they had religious objections.
Sen. Jeff Flake (R-AZ) also said he was glad Brewer vetoed the bill.
Thank you, @GovBrewer, for vetoing #SB1062
