Rep. Debbie Wasserman Schultz, D-Fla., stepped up to bat for former President Barack Obama on Tuesday after he was criticized for accepting $400,000 for a speech at a Wall Street firm's healthcare conference in September.

"Of all people to question ... their commitment to getting money out of politics, to really making sure we restored integrity to political finance process, President Obama couldn't have done more," Wasserman Schultz told CNN host Erin Burnett on Tuesday evening.

Wasserman Schultz, who was ousted as Democratic National Committee chairwoman last summer for colluding with Hillary Clinton's campaign, said Obama has a history of fighting "against the big banks," despite his decision to now accept a large sum of money to address the Wall Street group.

"Look, it is none of anyone's business what someone who is a member of the private sector decides to accept in terms of compensation," Wasserman Schultz added. "With all due respect to anyone who chooses to comment publicly on what Barack Obama, Hillary Clinton, or anyone earns as a member of the private sector, it's just MYOB."
