The Houston Airport System's work overseas building and running foreign airports was brought up in the city mayoral campaign today, the Chronicle's Brad Olson writes tonight, as candidate Gene Locke took shots at one of his opponents, City Controller Annise Parker:

Mayoral candidate Gene Locke sharply criticized opponent and City Controller Annise Parker on Thursday for a letter she wrote suggesting that a nonprofit affiliated with the Houston Airport System could cause the city severe financial problems.

At issue, Olson writes: Locke says Parker made a bigger deal of the HASDC issues than was necessary.

The letter Parker wrote caused the city to give a yellow-light to a planned sale of hundreds of millions of dollars in airport-related bonds. The city had to make some changes to its bond-sale literature to mention the HASDC issues so that possible bond buyers would have full disclosure of what was going on.
