A former aide to Chris Christie texted to a colleague that the New Jersey governor lied about the involvement of his senior staff and campaign manager during a news conference about the George Washington Bridge lane-closing scandal, according to a new court filing.

A transcript of the text is contained in court filings submitted late Tuesday by attorneys representing Bill Baroni, who faces trial next month with Christie’s ex-deputy chief of staff, Bridget Kelly, on charges they helped orchestrate the September 2013 lane closures.
