Gov. Rick Perry has sent an email to close friends saying he will announce his "exciting future plans" on Monday in San Antonio. 

  Perry previously said he would announce in early July whether he would run for re-election; he has also said a decision about whether to make another presidential bid won't come until the end of the year.    In the email obtained by The Texas Tribune and first reported by CNN, Perry invites supporters to join him and his family for an announcement at mid-day Monday in San Antonio. He does not specify a location for the announcement, and says details will follow.    It's looking increasingly unlikely that Perry will seek a fourth term in the Governor's Mansion; his gubernatorial campaign team has largely been disassembled, and his fundraising pales in comparison to that of his likely successor, Attorney General Greg Abbott.
