Harvard President Says Goodbye at Graduation

CAMBRIDGE, Mass. -- Harvard University President Lawrence H. Summers presided over his final commencement Thursday, enjoying a warm reception from students and later challenging the university to make bold use of its unmatched financial resources as it carries on under new leadership.

Set to leave office June 30 after five tumultuous years, Summers spoke at Harvard's 355th commencement to confer 6,706 degrees in rainy Harvard Yard.

Later, he told an audience of alumni he is proud of Harvard's progress during his tenure -- though he is disappointed it is ending.

"There was much more I wanted, felt inspired, to do," Summers said.

The former Treasury secretary announced his resignation in February; he had clashed with faculty after controversial remarks he made about women failing to reach the highest posts in scientific fields. He has said he will take a sabbatical next year and then return as a professor. Former Harvard president Derek Bok will lead the university while a successor is chosen.

Two More in Family Charged in Spy Attempt

LOS ANGELES -- Two more members of a California family have been indicted in connection with an investigation into an attempt to send sensitive information about Navy warship technology to China.

Wednesday's indictment by a grand jury in Santa Ana brought to five the members of a Chinese American family charged with being Chinese agents, the U.S. attorney's office in Los Angeles said.

Chi Mak, 65, an engineer at a Navy defense contractor; his wife; and his brother were indicted in November. Mak's sister-in-law Fuk Heung Li and his nephew Billy Yui Mak, 26, were indicted Wednesday.

None of the five has been charged with espionage because the material was not formally classified.
