Senators Sherrod Brown (D-Ohio) and Pat Toomey (R-Pa.), respectively the chair and ranking member of the committee, wrote a public letter to Bankman-Fried, who resigned from the exchange the same day it filed for bankruptcy last month.

“FTX’s collapse has caused real financial harm to consumers, and effects have spilled over into other parts of the crypto industry. The American people need answers about Sam Bankman-Fried’s misconduct at FTX," the lawmakers said in a prepared statement. "The Committee has requested that he testify at our upcoming hearing on FTX’s collapse, and will consider further action if he does not comply.”
