The chairman of the House Armed Services Committee said Monday he wants to see the cost of stationing U.S. troops on a permanent basis in Eastern Europe while at the same time drawing a comparison between the Trump administration's defense budget and the Obama administration's.

"I've asked for just a study of the costs," Rep. Mac Thornberry, R-Texas, said after giving a speech at the Brookings Institution, The Hill reports. "What are the estimates of what it would take to have a permanent unit there vs. the cost of rotations? We ought to know that information."

Thornberry was referencing the rotations the U.S. military serves with its fellow NATO members along the eastern edge of Russia. Tensions between Russia and both the U.S. and European nations have become heightened in recent years due to Russia's aggressive military moves.

According to the Washington Examiner, Thornberry called President Donald Trump's defense budget proposal "basically the Obama approach."

"I think that the budget that the administration will propose is roughly 3 percent more than what President Obama had suggested for this year. It's roughly a 5 percent increase over current year funding," Thornberry said during his Brookings speech, reports the Examiner. "So, I think it is fair to say it's basically the Obama approach with a little bit more, but not much."

Trump would like to see the military increased over the next several years, including a buildup of Naval ships and submarines.
