No. Max spoke with him and referred him to the Kerry campaign.
Parallels Drawn Between CBS Memos, Texan's Postings
excerpt:
Cleland confirmed that he had a two- or three-minute conversation by cell phone with a Texan named Burkett in mid-August while he was on a car ride. He remembers Burkett saying that he had "valuable" information about Bush, and asking what he should with it. "I told him to contact the [Kerry] campaign," Cleland said. "You get this information tens of times a day, and you don't know if it is legit or not."

I don't give much weight to Cleland's disclaimer at the end. He wouldn't refer just anybody to the Kerry campaign.
How did Burkett get Cleland's cell number?
