WASHINGTON
Squaring off with U.S. Rep. Jim Oberstar, National Transportation Safety Board (NTSB) Chairman Mark Rosenker made little effort to hide his discomfort.
"I have great respect for you," Rosenker told the Minnesota Democrat during a public hearing Wednesday. "And I don't enjoy being in your doghouse, believe me."
Oberstar, chairman of the House Transportation Committee, had come to the NTSB hearing armed with a list of questions about the government's investigation into the Interstate 35W bridge collapse in Minneapolis.
As he has before in their public feud, Oberstar made no secret of his displeasure with the NTSB's decision last month to forgo an intermediary public hearing on the causes of the collapse.
Wednesday's NTSB "reauthorization" hearing -- normally a routine annual budget review conducted by an aviation subcommittee -- would now serve as Oberstar's forum to press Rosenker to reconsider in public.
"It's a matter of courtesy to thank you," Oberstar said by way of welcoming Rosenker to the dais. "But it's your responsibility to be here."
That set the blunt tone for what turned into the most pointed examination in Congress yet of the course of the NTSB's investigation.
