Some workers may dream about how productive they'd be without a boss. But for thousands of federal employees, being without a boss is a reality. And productivity isn't necessarily the result.

Unless Congress acts, across-the-board spending cuts scheduled to take effect March 1 will be felt throughout the government. Some of the most visible effects will be noticed by air travelers.

Officials predict that cutbacks at the Federal Aviation Administration could lead to takeoff delays and fewer flights overall.

Every month, the government sends out about 5 million checks to Americans who receive federal benefits. On March 1, the Treasury Department is making those paper checks a thing of the past.

Since May 2011, all new Social Security recipients are required to get direct deposit of their benefits. Some 93 percent of all recipients now do.

But there are still holdouts, so the Treasury Department started a campaign and a website, Go Direct, in an effort to convince the remaining 7 percent.

President Obama's proposed renewal of a ban on assault-style weapons is expected to be based on the legislation approved by Congress in 1994 that expired 10 years later.

But when the first assault weapons ban was approved — outlawing 19 specific weapons — it was a very different time, and Congress was a very different place.

The nation's largest gun owners group had said little in the immediate aftermath of the shootings at Sandy Hook Elementary School in Newtown, Conn. But the National Rifle Association's executive vice president, Wayne LaPierre, broke that silence Friday with a call to place armed guards at all of the nation's schools.

But when it comes to helping out his district in southern Wisconsin, Ryan's principles have been flexible.
