(CNN) A group of President Donald Trump's most ardent supporters in the House of Representatives have sent a letter to the Norwegian Nobel Committee, formally nominating the President for a Nobel Peace Prize.

The nomination was spearheaded by Indiana's Rep. Luke Messer, who is locked in a fierce GOP primary battle in the Hoosier State for a Senate seat.

In the letter, Messer and his Republican colleagues endorse Trump's nomination by arguing that he deserves the award because of his work to end the Korean War and bring peace to the peninsula.

"Since taking office, President Trump has worked tirelessly to apply maximum pressure on North Korea to end its illicit weapons program and bring peace to the region," the letter reads.

Joining Messer in the letter are conservative members like Freedom Caucus leader Rep. Mark Meadows of North Carolina and Rep. Steve King of Iowa. Six of the signatories are seeking higher office, including Rep. Marsha Blackburn, the presumptive Republican nominee for Senate in Tennessee; Rep. Diane Black, who is running for governor in Tennessee; Rep. Evan Jenkins, who is part of a three-way primary for Senate in West Virginia; Rep. Jim Renacci, who's running for governor of Ohio; and Rep. Kevin Cramer, who is attempting to unseat Democratic Sen. Heidi Heitkamp in North Dakota.
