(CNN) Rep. Kevin McCarthy, the top Republican in the House, brushed off concerns about government spending at President Donald Trump's businesses on Tuesday, saying Trump's hotels are "just like any other hotel."

His comments come as House Democrats move to expand their impeachment investigation to focus on Trump's business dealings and questions of corruption.

"The President's resorts are hotels that he owns. People are traveling, it's just like any other hotel," McCarthy said at a Capitol Hill news conference Tuesday morning. "I don't know that that's different than anything else. Is it different if I go and stay or eat at a Marriott here, or eat at the Trump? The President isn't asking me to. He's competing in a private enterprise."

Trump did not divest from his interests in the Trump Organization upon entering office, prompting ethical concerns from Democrats who argue he is profiting from the presidency. Their criticism has ramped up in the past several weeks, as separate controversies have swirled around Trump's resorts.

First, he announced that he was considering holding next year's G7 summit at his National Doral resort in Miami. The proposal prompted Democrats on the House Judiciary Committee to announce on August 28 that they would investigate the matter.
