KHOU's Mark Greenblatt has been at the vanguard of exposing deep-seated problems at Houston Metro, the region's transit authority.

He was at a court hearing today invloving Metro today when this revelation exploded:

The president and CEO of the Metropolitan Transit Authority was accused in open court Wednesday of having an improper relationship with a female employee who works for him. That alleged relationship may include taxpayer-funded trips to Spain, additional compensation and benefits, and other items the public paid for with tax dollars, according to the attorney for former Houston Controller Lloyd Kelley.

Attorney Michael West, who represents Kelley, told Judge Al Bennett  he has information which leads him to believe Metro President Frank Wilson had substantial motivation to keep specific documents or e-mails from coming out.

Kelley had previously sued Metro, alleging it improperly destroyed public documents related to a public information request from Kelley.

KHOU grilled Metro CEO Frank Wilson on these allegations, but he remained mum.

KTRK's Ted Oberg has also been doing great work looking into the mess at Metro. Make sure to check out his latest report, as well as Texas Watchdog's video showing what it's like to be grilled by Oberg. (Hint: It ain't pretty if you're in his sights!)

We'll update as we learn more.
