Pueblo County Clerk Gilbert Ortiz on Friday began issuing marriage licenses to gay and lesbian couples, joining two other Colorado counties.

“Pueblo County acknowledges marriage equality and will begin issuing licenses at 8 am tomorrow,” Ortiz tweeted on Thursday.

Denver County Clerk Debra Johnson began issuing such licenses on Thursday.

“My Office issued 17 same-sex licenses to loving couples in #Denver today,” she tweeted. “Onward!”

Johnson and Ortiz are the first two county clerks to act after a Colorado judge ruled that Boulder County Clerk Hillary Hall can continue issuing marriage licenses to gay couples, though District Court Judge Andrew Harman said the validity of the licenses remains in question.

Colorado Attorney General John Suthers, a Republican, said he would appeal Harman's ruling to the Colorado Supreme Court.
