Texas Governor Rick Perry says people need to understand the details of his veto of money for a public integrity unit run by Travis County District Attorney Rosemary Lehmberg.

Perry said on "Fox News Sunday" every Texas governor has made such decisions for decades and he does not regret his decision after Lehmberg was arrested and pleaded guilty to drunken driving in April of last year.

When asked about a potential prison sentence, Perry says he takes the rule of law seriously.

He is facing two felony counts of abuse of official capacity for which he could face five to 99 years in prison and coercion of a public servant, for which he could face two to 10 years.
