Gov. Chris Christie’s former deputy chief of staff Bridget Kelly filed court papers on Thursday seeking to block a documents subpoena issued by the legislative committee investigating the Bridgegate scandal.

Like William Stepien, Christie’s former campaign manager who was also subpoenaed, Kelly has refused to comply based on her Fifth Amendment privilege against self-incrimination, her Fourth Amendment right against unreasonable searches and seizures and corollary protections provided by New Jersey law.
