WASHINGTON (AP) — Republican opposition to Obama administration plans to spin off U.S. oversight of the Internet’s domain name system is evolving into an election-year political fight, with GOP lawmakers using it as the latest front in their attacks on President Barack Obama’s trustworthiness.

“We’ve seen enough out of this administration and its imperial presidency politics that I’m not going to just give them a blank pen and then walk away,” Rep. Greg Walden, R-Ore., said Thursday as a House subcommittee he chairs voted to impose a one-year delay in implementing any changes so congressional investigators could study the issue.
