U.S. Sen. Tim Scott, who earlier called for VA Secretary Eric Shinseki to resign, praised his decision to leave today, saying it was an opportunity for "new leadership at the Department of Veterans Affairs."

"President Obama must name a new secretary who is a strong leader, proven manager and willing to be a true reformer," Scott said. "As this scandal continues to grow, the Department of Veterans Affairs must have a leader who will take these issues head on; our veterans deserve nothing less than the high quality, timely care they have earned."

Scott, R-S.C., last week joined with 24 other Senate members to call on the U.S. Senate Permanent Subcommittee on Investigation to launch "an immediate, independent investigation of mismanagement, incompetence and corruption" at the Department of Veterans Affairs.
