Sen. Judith Zaffirini spent about $58,800 on travel expenses and per diem payments over a year and a half period, outspending her state Senate colleagues. That's based on a review of electronic travel records from Jan. 1, 2008, to May 1, 2009, that Texas Watchdog used as the basis for a blog item on her spending yesterday.

Texas Watchdog originally reported a higher, incorrect total for Zaffirini's spending. We apologize for the error.

We arrived at the figure based on numbers in two spreadsheets, which had been compiled by the secretary of the senate's office and provided under the Texas Public Information Act. Overnight per diem payments to senators appeared in both spreadsheets, and unfortunately, we didn't catch that duplication before we did the first tally.

Also, after double-checking the figures, Sen. Kirk Watson still came out spending the least, at more than $21,000.
