Republican opponents of Ohio Sen. Sherrod Brown are speaking out over what they claim is a plan to “gut” social security benefits and potentially raise the retirement age in the US. 

“Sherrod Brown, Kamala Harris and Tim Walz will gut social security and raise the retirement age, and won’t fight for our seniors,” Brown’s Republican opponent, Bernie Moreno, told The Post.

“While Brown, Harris and Walz will curb these benefits, President Trump, JD Vance, and I will ensure social security is not taxed and that seniors receive the benefits they were promised.”

In 2010, Brown was lambasted for endorsing recommendations for the controversial Simpson-Bowles Commission, which proposed raising the retirement age to 69.

He has also voted for multiple tax hikes on social security and against multiple tax repeals in his two-decade run on Capitol Hill.

As far back as the 1993-1994 Congress, Brown was a proponent of budgetary measures with legislative riders that included new restrictions to Social Security — restrictions that did not ultimately move forward.

Between 2007 and 2009, Brown voted against three separate bills that would have lowered existing taxes on social security payouts.

That pattern, coupled with the sudden ascendancy of candidates like Harris and Walz to national prominence, has Ohio GOPers eager to alert the rest of the nation: your retirement may not be safe.

“Sherrod Brown voted repeatedly to raise taxes on social security. He was also supportive of a plan to raise the retirement age and slash retirement benefits for seniors. Those are positions he will need to explain to Ohio seniors,” NRSC Spokesman Philip Letsou told The Post.

The Harris-Walz campaign told Fox News that Walz has “no plans” to raise the retirement age.

Brown’s office also declined comment.
