Arizona U.S. Sen. John McCain used his time on CBS's "Face the Nation" Sunday to voice dissatisfaction with how the White House is handling the crisis between Russia and Ukraine, going so far as to say he is "ashamed" of his country and himself.

"I'm ashamed of my country, I'm ashamed of my president and I'm ashamed of myself that I haven't done more to help these people," McCain said. "It is really, really heartbreaking."

McCain was referencing what he believes is a failure on behalf of the U.S. and its European allies, like Germany and France, to successfully manage Russia's alleged intervention in Ukraine.

"I believe that German chancellor and president of France legitimized for the first time in 70 years the dismemberment of a country in Europe. It's shameful. Vladimir Putin has not paid any price," McCain said, reported The Washington Times.

McCain called for the Obama administration to send military weapons to the Ukrainian government to help in its fight against pro-Russian separatists, something President Obama has not yet decided on.

"The Ukrainians aren't asking for American boots on the ground. That's not the question here. They are asking for weapons to defend themselves," said McCain, chairman of the Senate Committee on Armed Services. "They are being slaughtered and their military is being shattered."

The presidents of Germany and France led 16-hour-long peace talks between the presidents of Russia and Ukraine two weeks ago, which ended with the establishment of a ceasefire and peace deal, but the fighting has continued.

Germany commented Monday, saying it is "extremely worried" that the ceasefire and peace deal has not been upheld as fighting continues along the Ukrainian-Russian border, Reuters reported.
