State Controller John Chiang was undergoing tests at a Texas hospital Monday after experiencing chest pains while visiting family for the holidays.
Spokeswoman Hallye Jordan said Chiang checked himself into Harris Methodist Hospital in Fort Worth on Friday and was resting comfortably.
She said she did not know whether the 46-year-old controller had any past medical problems.
Chiang, a Democrat, serves as California's chief fiscal watchdog and has said the state will run out of money in February unless the governor and lawmakers act.
