HARTFORD, Conn. (AP) Gov. Dannel P. Malloy is continuing to voice concerns about proposed changes to rules granting federal recognition to American Indian tribes.

Malloy told The Associated Press Monday he met privately with Vice President Joe Biden about the issue for about 45 minutes during his four-day visit to Washington, D.C.

Malloy and other state officials are worried about making it easier for groups petitioning for federal recognition to gain acknowledgement.  Malloy said he wanted to ensure Biden "understood that our state is a state that could be adversely impacted.''  Some of the concerns are about the Kent-based faction of the Schaghticoke Indian Tribe.

The existing federal regulations overseeing the federal recognition of tribes were originally adopted in 1978. They've been updated once in 20 years.
