Social security has been a major topic of conversation for both Democrats vying to be president and Donald Trump himself this week. Bernie Sanders attacked Biden today on the issue and the former Vice President clapped back.

Indeed Trump hinted at cutbacks during a Fox News town hall with Martha MacCallum Thursday night, during this exchange:

“[I]f you don’t cut something in entitlements, you will never really deal with the debt,” MacCallum told Trump.

“Oh, we’ll be cutting,” the president replied.

He later tried to walk the comments back.
