New Jersey Gov. Chris Christie says he’s disappointed the US Supreme Court has upheld key parts of President Obama’s federal health insurance overhaul.

But Christie did not say whether he would move ahead with a state health-insurance exchange called for under the federal law.

Christie vetoed an exchange last month, saying he wanted to wait for the court ruling before committing money to it. At the time, the governor said he would move ahead with the state’s part of the deal if the law was upheld.

But in a statement Thursday, Christie did not reiterate that.

A spokesman would not elaborate immediately.

State Sen. Nia Gill on Thursday said she would reintroduce legislation to establish the exchange.
