I asked you to cite where Sanders himself, not a surrogate, called her, personally, corrupt. That hasn't happened. He's calling the finance system corrupt. He did say this in one of your links Emphasis Mine.:
You think a $350,000.00 a ticket "fund raiser" for anybody isn't obscene? It is horrifically obscene. If I were a Hillary apologist and wanted to have her make inroads with Sanders supporters, when asked about that comment, I'd tell her to say, "Yes. Senator Sanders is correct. A 350K per seat fundraiser is obscene. I hate it, but until we change campaign financing the way I want to change it, this is what must be done. I am as much a victim of this process as anyone." It would ring hollow, of course, but that's on the candidate.
Your second link offering opinions that match yours, also without any direct citations, is equally uninspiring.
Speaking to CNN, Mr Sanders said it was "obscene that Secretary Clinton keeps going to big-money people to fund her campaign".

“I have a lot of respect for George Clooney. He’s a great actor. I like him,” Mr Sanders said. “But this is the problem with American politics.
"It’s not a criticism of Clooney. It’s a criticism of a corrupt campaign finance system, where big money interests... have undue influence on the political process.”
