My LO was given fed time conc. to his current state case. He was given a new state term to be ran consec. Will the fed time stop or continue to consec

I just want to know if he was serving a state sentence and was given his fed time to be served concurrent to the state term he was serving. After he was sentenced with the Feds he was sentenced consecutively for another crime prior to being arrested. Will the federal time be ran concurrent on that or consecutively since the second case wasn’t specified on his plea agent with the Feds only the one term he was already serving.
