Which was not a reason johnson used when vetoing the extension of the freedmen''s bureau and the civil rights bill of 1866?

Assuming that this is referring to the same list of options that was posted before with this question, "the fact that it was seen as too great an expenditure" was not a reason, since Johnson opposed the program mostly based on the fact that it was an incursion on rights.

If he breaks the law then he had to resign from his post and so he'll lose his/her powers.
