(CNN) - California Sen. Barbara Boxer told CNN Sunday she and her Senate colleagues are "worried" about the possibility of transferring current Guantanamo Bay detainees into the United States, adding she is awaiting a more comprehensive plan on the matter from President Obama.
"We only have one max security prison in California and it's, right now, overbooked, that's the case," Boxer told CNN's John King on State of The Union. "In all, we are worried and we want to to see what the plan is."
Boxer's comments come days after Senate Democrats voted to withhold funding to close the Guantanamo Bay facility until the president lays out a more detailed plan on where the current 240 detainees will go.
Alabama Sen. Richard Shelby, also appearing on State of The Union, cautioned the president against relocating the most "incorrigible" detainees in the United States.
"Nobody wants them. We got all kinds of places in the world we can house these people," Shelby said. "If we have to move them from Cuba, from Gitmo, we have other territory that can bring them in, but don't bring them to the United States of America.
In a high profile speech Thursday, Obama pledged no detainees would be brought to the United States "if it would endanger our national security."
