PROVIDENCE, R.I. -- Former Red Sox pitcher Curt Schilling says he doesn't know what he should apologize for following the collapse of his video game company that received a $75 million loan guarantee from Rhode Island.

Schilling did his first interview about 38 Studios on Tuesday with WPRO-AM.

He asked listeners: "What do you want me to apologize for?"

Democratic Gov. Gina Raimondo has said Rhode Island residents were hurt by the bad deal and deserve an apology.

Schilling says his company failed because it didn't raise enough money, not because he did anything malicious or illegal.

Schilling also says he'll run against Democratic U.S. Sen. Elizabeth Warren in 2018, if his wife agrees.

38 Studios moved from Massachusetts to Rhode Island in 2010 in exchange for the loan guarantee, then went bankrupt.

The state sued. A judge recently approved a settlement with Schilling.
