Veterans Affairs Secretary Eric Shinseki took to the opinion page of USA Today on Thursday to outline everything he's doing to fix the "reprehensible" scandal plaguing his department. It's a start, but probably not enough to stop the growing list of members of Congress calling for his head. (Update: Shinseki has resigned.)

As soon as Wednesday's preliminary report from the VA's Office of Inspector General found that delayed medical care to veterans and cooked books is "systemic throughout" the nation's VA hospitals, many members of Congress who were on the fence quickly called for Shinseki to step down. Here's a list of every member of Congress calling for him to resign, or for President Obama to force him to resign. (Updated Friday 11:37 am)

Republicans

Sen. Richard Burr

Burr, the top Republican on the Senate Veterans Committee, drew the ire of several veterans groups when he criticized them for not calling for Shinseki's resignation. "I must recognize and commend ... the American Legion team for taking a principled stand, before the hearing and during it, and calling for leadership change at the VA," he wrote.

Sen. Jeff Flake

Sen. Rob Portman

Sen. John Boozman

"The public, a large portion of the veterans’ community, and much of Congress have lost faith in Secretary Shinseki's ability" to solve the problem, Boozman said in a statement. "The administration must take quick action to regain that confidence .. While a leadership change at VA is in order, a new secretary alone will not absolve the President of his responsibility to ensure our veterans receive quality care in a timely manner."

Sen. John McCain

McCain was initially hesitant to call for Shinseki to step down until all the facts were in, but after the IG report confirmed concerns that the VA's problems are widespread, he reversed course on CNN Wednesday“I have not called for it. I was going to wait until the hearing that’s going to take place here very soon," McCain said. "I haven’t said this before, but I think it’s time for General Shinseki to move on.”

Sen. Tim Scott

Sen. Marco Rubio

Sen. Mitch McConnell 

Sen. Jerry Moran 

Moran called for Shinseki's resignation on May 6

Sen. Pat Roberts

Roberts called on Obama to fire Shinseki, arguing that “accountability is a virtue sorely lacking in the Obama Administration. From Benghazi to Fast and Furious, the IRS scandal to the rollout of Obamacare, President Obama has been long on words, but short on action." 

Sen. Deb Fischer

Sen. Dean Heller

Sen. Kelly Ayotte

Ayotte called for Shinseki to resign last week, according to The Concord Monitor.

Rep. Steve Pearce

Rep. Robert Pittenger

Rep. Diane Black

Rep. Alan Nunnelee

Rep. Richard Nugent

"Frankly, at this point, I believe the strongest leadership that Secretary Shinseki could show in this regard is to resign.  It’s simply gone too far," Nugent said in a statement Thursday afternoon. “I want employees at the VA nationwide to understand that this is not a witch hunt to come after anybody.  But if you know of wrongdoing, this is your time to come forward."

Rep. Randy Forbes

Rep. Erik Paulsen

Democrats

Sen. Mary Landrieu

"Shinseki served our nation with distinction but recent unacceptable actions under his watch regrettably means new leadership is needed," Landrieu tweeted late Thursday afternoon. "It will take a new leader with effective tools to fix these systematic #VA problems and provide the quality care our veterans deserve."

Sen. Mark Begich

Begich will hold a press conference on Thursday, according to Politico. He's up for re-election this year.

Sen. Al Franken

Sen. Martin Heinrich 

Heinrich said he has a "mountain of respect" for Shinseki, but “I call on President Obama to appoint a new Secretary."

Sen. Kay Hagan

Hagan was "outraged" by the findings of the IG report, and “in the interest of regaining the trust of our veterans, and implementing real and lasting reforms, I believe it is time for him to step aside and allow new leadership to take the helm at the VA to correct these failings immediately.” Hagan is seeking re-election this year.

Sen. Mark Warner

Rep. Tammy Duckworth

Duckworth, a former Veteran Affairs official and veteran, said Friday her former boss should step down to direct the conversation back to veterans:

Our first priority should be the veterans and at this point whether Secretary Shinseki will stay or go is too much of a distraction. I think he has to go. He certainly loves veterans, but it's time for new leadership, it's time to get someone in who will put veterans first. We've moved away from veterans being the primacy of the conversation. It's now a political discussion and that's now where it should be when it comes to our nation's heroes.
