“We just get bogged down in the Middle East and Russia will get bogged down in the Middle East," Trump added.
Trump's views on Syria have been panned by other Republicans, including Sen. John McCain (R-Ariz.), the chairman of the Senate Armed Services Committee, who suggested on Sunday that the real estate tycoon did not understand the situation there.
President Obama also blasted the Russian airstrikes in Syria that began last week, accusing Russian officials of being indiscriminate in airstrikes against ISIS and U.S.-supported moderate Syrian rebels.
The situation escalated this week, with Russia saying Monday that its "volunteer" ground forces would join the fight in Syria, according to The New York Times.
The Obama administration has long called for Syrian President Bashar al-Assad to step down as the U.S. and international community work to pick up the pieces of a brutal four-year Syrian civil war.
"I'm sure Assad is a bad guy, but you can have worse," Trump said Tuesday on CNN.
"We're not trusting Russia," he insisted. "You're not hurting yourself by watching and waiting."
