Cummings: "I am reminding you that you are under oath"

Rep. Elijah Cummings (D-Md.) just completed the opening round of questioning, and he focused almost solely on Roger Clemens. It amounted to a public flogging.

Cummings focused largely on Andy Pettitte's testimony and affidavit. He said that because of inconsistencies between Clemens's testimoney and that of Pettitte, they went back to Pettitte a total of three times. Pettitte told the investigators that he and Clemens had a conversation in either 1999 or 2000 about Clemens's use of HGH. When the two talked about it again in 2005, Clemens denied it.

Cummings used Clemens to establish Pettitte's trustworthiness.

"Andy Pettitte is my friend," Clemens said. "He was my friend before this. He will be my friend after this. And again, I think Andy has misheard."

Cummings read from Pettitte's testimony:

"I must have misunderstood him," Cummings read from Pettite's remarks. "He claimed taht it was his wife Debbie who used HGH. I said, 'OK,' or words to that effect, not because I agreed with him, but because I didn't want to remind him."

Pettitte's testimony also included that he shared all these conversations with his wife, Laura. The committee received an affidavit from Mrs. Pettitte that confirmed her husband's accounts.

Cummings asked Clemens: "Has your mind changed about his credibility?"

"Andy's a fine gentleman," Clemens responded. "I think he misremembers."

Rep. Tom Davis (R-Va.), the ranking member of the committee, is grilling now.
