Friday will be our fourth day in the United States under a federal government shutdown. Rep. Eric Cantor says he will announce the weekend schedule on Friday morning, which delays any plans of Congress and its staff members to escape from Washington, DC. If Congress does continue to meet over the weekend, the pressure of working over the weekend may encourage a speedier resolution to the federal budget crisis.

Boehner says the government shutdown "is not a game."

Rep. Eric Cantor: House will vote for federal employees to receive pay after federal shutdown on Saturday, confirming that Congress will continue its work in Washington, DC through the weekend.

House leadership says it will also vote to re-open FEMA, the National Weather Service and Head Start programs in mini-funding bills outside of a "clean" (or comprehensive) continuing resolution to fund the federal government.

This continues the GOP strategy of approving funding bills agency by agency.

An incredible report from late yesterday: Washington, D.C. is not able to pay hospitals, long-term care providers and other organizations that participate in the Medicaid healthcare program for the poor during the federal budget shutdown. Read more: www.reuters.com

Howard Goller, Washington Editor, Reuters Professional News reports: Republicans may have made a mistake from a public relations standpoint allowing the government to shut down on the very day Obamacare was launched, says the Washington author of a new book tracing 200 years of popular culture and the U.S. presidency.

Asked what headline he would write to describe what happened this week, author Tevi Troy said, "I would say: 'Obamacare opens with glitches, but nation focuses on shutdown.'"

A former deputy secretary of Health and Human Services in the George W. Bush administration, Troy said: "For every health nerd ... this is our Super Bowl, and the headlines were about the shutdown."

"So from the GOP perspective, that was a lost communications opportunity. That was an opportunity to shape the message on the Affordable Care Act ... and the above-the-fold headlines were about the shutdown," he said on Thursday.

Despite the shutdown, Republicans have failed to derail Obama's signature healthcare law, which passed a milestone on Tuesday when, in spite of glitches, it began signing up uninsured Americans for subsidized health coverage.

Obama, a Democrat, has blamed the shutdown on Republicans' "obsession" with reversing healthcare reforms. Opinion polls show Republicans bearing the brunt of the blame, but Troy believes Americans want both sides to work it out.

"I think the American people don't like it when the two sides don't sit down ... If they had the feeling they were sitting down discussing this behind the scenes, the American people would be a little less annoyed, or disgusted."

Troy is the author of "What Jefferson Read, Ike Watched, and Obama Tweeted: 200 Years of Popular Culture in the White House," published last month.

In absolutely non-essential political news, the journo-Twitterazi are fascinated by President Obama and Vice President Biden's lunch choice today.

Global economic systems react to the second week of the partial U.S. federal government shutdown:

Mexican stocks fell more than 1 percent on Monday on concerns over the continued U.S. government shutdown and political fighting over the debt ceiling limit.

A lack of progress by U.S. lawmakers in budget and debt ceiling talks rattled investors on Monday, sending European shares to a four-month low and pushing the dollar and oil down. Low-risk euro zone bonds inched up on Monday, with investors nervous about the lack of progress in resolving the U.S. budget standoff as a mid-October deadline for raising Washington's debt ceiling approaches.

Finland's European Affairs and Foreign Trade Minister Alexander Stubb said the global economic impact of the shutdown was worrying: "To be quite honest, what the Republicans are doing in the U.S. right now, especially conservative Republicans, is irresponsible from a global perspective. ... They're trying to get a short-term political gain which might hit both the United States and the rest of the world economically."

South Africa's finance minister said the global community should fear the worst over the U.S. debt crisis and shore up its economic defenses accordingly.

Notes: President Obama's remarks on the federal shutdown at FEMA

President Obama called on House Republican leadership to bring a "clean" government funding bill in remarks on Monday at the Federal Emergency Management Agency (FEMA) and urged Congress to raise debt limit and avoid default. President Obama says FEMA job has been made more difficult by government shutdown, adding that FEMA will refurlough 100 workers who had been recalled to help with tropical storm preparation.

Obama said he is happy to talk to Republicans about anything but not under the threat of shutdown or default, saying there are enough Republican and Democratic votes in the House to end the shutdown. He called for the House to bring a floor vote today.

Obama said it is his "very strong suspicion" that there is enough support in the House to pass a clean continuing resolution (CR) to reopen the federal government, telling reporters that the House should "call a vote right now. Let's see what happens."

Obama is "eager" to sit down with Republicans to talk about health care and other issues once the debt limit is raised, stating that Democrats have already compromised by accepting Republican demands about spending levels that are lower than Democrats would have otherwise liked.

Replying to a question on Thursday, President Obama says that U.S. Treasury Secretary Lew will make prepared remarks to the Senate on the legal implications of a U.S. default and debt prioritization -- or the process by which the government would use to decide which bills to pay before others, so to speak.

Reuters Thomas Ferraro reports: Republican U.S. Senator John McCain on Tuesday said he opposes a demand by President Barack Obama and his Democrats in Congress for an unconditional increase in the U.S. debt limit. McCain, one of the more influential members of Congress, said, "The answer to this is negotiations."

Democrats had been citing McCain as a possible key vote to get their debt limit bill passed in the Senate. McCain, the Republican 2008 presidential nominee, told reporters Republicans must go into negotiations with a plan of what they want in return for raising the U.S. borrowing authority.
