U.S. Senator Tim Scott has joined the ranks of Republicans calling for embattled Veterans Affairs Secretary Eric Shinseki to resign, according to a news release issued by Scott's office Thursday.

If Shineski won't resign, Scott, says, President Barack Obama should immediately fire him.

Scott, R-S.C., said he is calling for Shineski's ouster because of mounting evidence of what the VA inspector general calls "systemic" problems at VA medical facilities.

"While Secretary Shinseki is a distinguished American solider and I appreciate his service to our nation, it is time for new leadership at the U.S. Department of Veterans Affairs," Scott said in the statement. "Every day, we hear more and more accounts of mismanagement, incompetence and corruption contributing to the deterioration in health or even death of some of our brave veterans. Our veterans and their families deserve better than 'secret' waiting lists, shredded official documents and other nefarious activities in order to cover up backlogs of veterans' claims."

Last week Scott and 24 other senators called on the Senate's Permanent Subcommittee on Investigation to launch an immediate, independent investigation of mismanagement, incompetence and corruption at the Department of Veterans Affairs.
