Home Depot co-founder Bernie Marcus hit back at liberals boycotting the home improvement chain over his plans to significantly contribute to President Donald Trump's re-election campaign.

Writing on Facebook this week, Marcus said celebrations honoring his 90th birthday — which included $117 million being donated to his favorite four charities — were ruined by those upset over his declaration to support Trump's re-election efforts.

"All because I give my voice and some of my money to our President. Am I in China? Argentina? Russia? That's what it feels like to me," Marcus wrote.

"It saddens me that our country has come to this, where I, as a private citizen, cannot express my feelings," he added. "It angers me and it saddens me, but it sure as hell is not going to stop me. If you thought it would, you've got the wrong guy."

"In the next ten years, God willing, I will accomplish more to save this world than my critics will do even if they had forty lifetimes," Marcus went on to say.

Marcus told the Atlanta Journal-Constitution last month that he plans to contribute the vast majority of his nearly $6 billion fortune to charity. But, he will also spend a significant sum on helping Trump win re-election, Marcus told the newspaper.

In response, liberals began boycotting Home Depot, despite the fact that Marcus retired from the company nearly 20 years ago.
