"To attack his integrity in order to protect the president is unacceptable. Furthermore, it is equally unacceptable for the president or any of his advisers to be thinking about granting pardons to those people who pled guilty," he told CNN's Jake Tapper on "State of the Union." 

The senator also warned that the president could provoke a "constitutional crisis" by granting pardons to those who have already been indicted as part of the investigation.

The president's former national security adviser, Michael Flynn, pleaded guilty earlier this month to lying to the FBI about his foreign contacts.  

Sanders's comments come as speculation swirls over whether the president will fire Mueller in the middle of the federal probe into alleged ties between the Trump campaign and Russia's election meddling. 

The president and the White House have dismissed speculation that Mueller would be fired, but Trump has ripped the probe, calling it a "witch hunt." 

Republicans have also criticized the probe, citing text messages that were critical of Trump from FBI agent Peter Strzok during the campaign. 

Strzok has since been taken off of Mueller's probe. 

A number of Republican lawmakers, including Rep. Trey Gowdy (R-S.C.), have urged the president not to fire Mueller, however. 

“He’s the best hope for giving us a product that the largest number of Americans can accept as credible,” Gowdy said.
