I have no idea on either case on non-Beltway relationships. What I do know is that both Reed and Chafee (Whitehouse came afterward) put extreme pressure on DoJ every time a CVS project came through, and that's cozy enough. The case I know most of all was when the DoD TriCare management contract left Medco and went to Caremark, CVS made it a priority acquisition target over antitrust warnings from DoJ. The entire RI delegation did their political jobs and kept DoJ off CVS's back. CVS scored Caremark for that contract (although the jury is out whether or not CVS made money or just kept market share, that's Woonsocket accounting for you).
I do agree that while they may not privately like each other, it's political suicide in RI to be anti-business due to Providence's decline. Unless there is something incredibly unusual, no politician in their right mind is going to screw up getting things done for NS Newport (sub base), CVS, Hasbro, or Royal Bank of Scotland - CFG.
