Sen. Roger Marshall (R-KS) endorsed former President Donald Trump for president in 2024 on Monday and called for the end of the "political primary charade."

Marshall, a longtime ally of Trump, said he was supporting Trump because he wants to dismantle the New Green Deal, boost farmers, and close the border, among other priorities.

"Since the day Joe Biden stepped foot in the Oval Office, this White House declared war on American agriculture and American energy independence in pursuit of their Green New Deal agenda and electric vehicle mandates," Marshall said in a statement to Fox News Digital.

"Joe Biden declared war on American sovereignty by opening our borders, ceding control to the cartels, allowing nearly 10 million illegal aliens into our country, and permitting lethal fentanyl to pour into our communities," he continued.

Only Trump can fix things

"Our farmers and ranchers feed the world, and Kansans deserve a President who understands that, and a leader who values the energy Americans produce. 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."

About a dozen Senate Republicans have already endorsed Trump along with 80 in the House.

The likely nominee

Trump has been consolidating his support among the GOP rank and file as well.

The latest Fox News poll showed that 62% of Republicans supported Trump, while only 14% supported Florida Governor Ron DeSantis and another 11% supported former South Carolina Governor Nikki Haley.

Trump's huge lead makes him the likely GOP presidential nominee, even as he faces four indictments and two civil trials.

The majority of Republicans think he's being railroaded by politically motivated prosecutors and possibly judges as well.

It's telling that Biden is getting a pass for his collection of classified documents, while Trump faces charges over his alleged ones.

So far, the legal issues haven't dampened his support and may have even increased it. As far as what will happen if he is convicted on any of the 90 separate criminal charges he faces, well, only time will tell.
