Lawmakers aren't any closer to reaching a budget deal, with only a week left to avoid a government shutdown.
Discussions are continuing on Capitol Hill this week but the finger of blame is already being pointed on both sides of the political aisle.
Last week, the Republican-controlled House voted to fund the government but defund Obamacare.
Sen. Ted Cruz is pushing for that bill in the Democratically controlled Senate.
"I believe we should stand our ground and I don't think Harry Reid and Barack Obama should shut down the federal government," Cruz said during a weekend interview on Fox News. "Look, the House voted to fund the federal government. If Harry Reid kills that, Harry Reid is responsible for shutting down the government"
"And he should listen to the American people, open the government, fund the government, but don't fund Obamacare because it's hurting the American people. It's not working," he added.
A plan to defund Obamcare is not expected to pass the Senate. Missouri Sen. Claire McCaskill is among the Democrats who oppose the idea.
"Well, it's not brute political force that is refusing to defund Obamacare. It's called the American people and elections," McCaskill said on Fox News Sunday. "I don't think in America, we should throw tantrums when we lose elections and threaten to shut down the government and refuse to pay the bills."
"The American people had a choice last November. They had a choice between someone who said repeal Obamacare and President Obama," she said.
