ALBUQUERQUE, N.M. (AP) – Republican New Mexico Gov. Susana Martinez says she won’t support Libertarian presidential candidate and former New Mexico Gov. Gary Johnson.

The nation’s only Latina governor, who has not endorsed fellow Republican Donald Trump, said Wednesday she disagrees with Johnson’s stance to reduce the nation’s military. Martinez also said as a former prosecutor she couldn’t support Johnson’s plan to legalize marijuana.

Johnson recently won the presidential nomination of the Libertarian Party and is seeking the support of Republicans who feel uncomfortable with supporting Trump.

Last week, Trump attacked Martinez at an Albuquerque rally for the number of state residents on food stamps.

Martinez, who is the chair of the Republican Governors Association, has criticized Trump for past comments about Mexican immigrants. She also says she wanted to hear how Trump would defend the state’s federal military bases.
