• Larry Summers has addressed the row about Harvard student groups that signed an anti-Israel letter.
• The letter, signed by 30-plus groups, said the students held Israel responsible for Hamas attacks.
• The ex-treasury secretary said, "Many in these groups never saw the statement" before it was sent.

Larry Summers, former US treasury secretary and Harvard graduate, said some of the students at the college who signed an anti-Israel letter "did not exactly understand what they were approving." 

Summers posted on X on Wednesday to share his stance on the situation and wrote, "I yield to no one in my revulsion at the statement apparently made on behalf of 30 plus @Harvard student groups. But please everybody take a deep breath."
