That is why I’m endorsing President Donald Trump. While others may try to imitate him, only President Trump will put our country back on track on day one,” he said.”Along with the onslaught of strangling regulations, Joe Biden declared war on our economy by unleashing a level of federal spending never seen in modern history, causing the highest inflation and interest rates that we’ve seen in decades,” he said.He added, “It’s time for the GOP to unite behind President Trump. Let’s end the political primary charade and focus on retiring Joe Biden.”RAMASWAMY CLASHES WITH CNN ANCHOR PRESSING HIM ON TRUMP’S ‘VERMIN’ COMMENTS: ‘GIVE ME A BREAK!’ President Biden, left, and former President Trump.
