But Carson argued that the writers of the U.S. Constitution addressed the need for policy change through elections, not secession.
The petition's success brought overnight fame for Hurd, though briefly got him in trouble. In December, a regiment commander at the Texas National Guard sent an email to his subordinates, including Hurd, saying "any mention of secession better happen on a civilian venue."
"It's only talk, and rather ignorant talk at that," the commander wrote. "If you've already done something to call attention to yourself or our regiment in this matter, make it go away."
But a few days later, a National Guard spokeswoman said Hurd had done nothing wrong and that "the email asking him not to talk about it" shouldn't have been sent.
A telephone listing for Hurd couldn't be found Monday by The Associated Press. His father, who has spoken on behalf of his son in the past, didn't immediately return a phone message.
