Sanders's victory follows rising tensions between the two candidates after he questioned Clinton's qualifications to run for president, a remark that snowballed into a weeklong dispute. 
 
He said Wednesday that her super-PAC support, Iraq War vote and support of trade agreements made her unqualified. The campaign doubled down a day later, arguing that Clinton and her allies had insinuated that Sanders himself wasn't qualified to run, but she brushed aside those accusations. 
 
The argument appeared to die down Friday when Sanders said that "of course" Clinton is qualified. 
 
Entering Saturday, Clinton led the race with 1,280 pledged delegates to Sanders’s 1,030, according to The Associated Press.
 
In addition, Clinton has 469 superdelegates to Sanders's 31.
