DNA testing has established, “with scientific certainty,” that Hunter Biden is the father of an Arkansas baby, according to a motion filed Wednesday in Independence County on behalf of the child’s mother, Lunden Alexis Roberts.

Biden, son of former vice president Joe Biden, “is not expected to challenge the results of the DNA test or the testing process,” the filing states.

An attorney for Hunter Biden, former Arkansas Attorney General Dustin McDaniel, did not immediately respond to a request for comment.
