(Bloomberg) -- Bernie Sanders kept up his challenge to Joe Biden’s claims that he never proposed cuts or freezes to social security.

“Joe Biden continues trying to hide his efforts to help Republicans cut Social Security,” Faiz Shakir, Sanders’ campaign manager,  said in a statement.

The campaign pointed to instances throughout Biden’s career in which the former vice president suggested cutting or freezing Social Security benefits including a 1995 vote for an amendment to the balanced budget bill which would have frozen Social Security expansions.

Both Biden and Sanders are running for the Democratic presidential nomination on a platform of protecting Social Security. Biden has said his plan to shore up Social Security would expand the program. Sanders has called on expanding benefits from the retirement program.

(Disclaimer: Michael Bloomberg is also seeking the Democratic presidential nomination. He is the founder and majority owner of Bloomberg LP, the parent company of Bloomberg News.)
