t from Democrats, who charge it would "end Medicare as we know it." The Senate rejected it in a vote last week, but also unanimously struck down an alternative plan proposed by President Obama.  Democrats said they wanted to leave it off the table while Vice President Biden leads a bipartisan group of senators to come up with a new budget that would include cuts in spending that would satisfy lawmakers who don't want to increase the nation's borrowing limit without reducing government's size. "The one thing we can't do is nothing," McConnell said. "The president, to his credit, is at the table. ... We're going to negotiate the contours of the plan in these negotiations. I'm personally very comfortable with the way Paul Ryan would structure it in the out years, but we have a Democratic president. We're going to have to negotiate with him on the terms of changing Medicare so we can save Medicare." Appearing on the same program, Sen. Chuck Schumer, D-N.Y., called on Republicans to abandon the House Medicare plan, noting an analysis by the nonpartisan Congressional Budget Office that says it would require seniors to shoulder an increasingly large share of their health care costs. Schumer said there are only three options -- doing nothing, the Ryan plan or a Democratic vision that preserves benefits and changes "delivery systems," but does "not let providersr China and South Asia, said Tuesday. Midha also said China is now Dell's second-biggest market by revenue and the company plans to double its number of service centers in the country to 2,000 this year. There are currently 15,000 retail stores selling Dell products in China and the company has to boost that number to increase its presence in smaller Chinese cities, he said. Dell last year announced plans to op "The list of targets just grows and grows." Lockheed Martin Corp. said in a statement Saturday that it detected the May 21 attack "almost immediately" and took countermeasures. "Our systems remain secure; no customer, program or employee personal data has been compromised," the Bethesda, Md.-based company said. Neither Lockheed Martin nor federal agencies would reveal specifics of the attack, or its origins. Company spokeswoman Jennifer Whitlow declined to comment further on the case Sunday. This isn't the first time Lockheed Martin has been targeted. Nearly four years ago, officials revealed that hackers had breached Lockheed's Joint Strike Fighter program. Officials said no classified information about the military program was compromised, but heightened protections were added. Analysts said the latest attack would likely spur rival defense contractors like Northrop Grumman Corp., Raytheon Co., General Dynamics Corp. and Boeing Co. to take additional steps to safeguard their systems. "I guarantee you every major defense contractor is on double alert this weekend, watching what's going on and making sure they're not the next to fall victim," Shaul said. Boeing declined to comment on the company's network security measures. Northrop Grumman spokesman Randy Belote said in an e-mailed statement that "we do not comment on whether or not Northrop Grumman is or has been a target for cyber intrusions," adding that the company "continuously monitors and proactively strengthens the security of our networks." Over the past several years, the U.S. government has become more aggressive in its efforts to tackle cybercrime, developing strategies to beef up government computer systems, expand cooperation with other countries and improve coordination with the private sector. President Barack Obama declared cybersecurity a top priority shortly after taking office in 2009, setting off several government-wide reviews to develop strategies to better secure government, business and public online activity. The Pentagon last May set up a new Cyber Command, based alongside the National Security Agency at Fort Meade, Md., in recognition of the expanding threat against the Defense Department and the need to better coordinate the nation's offensive and defensive cyber operations. The Department of Homeland Security is also slowly employing an automated system — known as Einstein 2 and Einstein 3 — to protect government agencies' computer systems. Still, the attacks have continued. William J. Lynn III, the deputy defense secretary, said in January that more than 100 foreign intelligence agencies have tried to breach U.S. defense computer networks, largely to steal military plans and weapons systems designs. China is often pointed to as a source of cyber attacks because a large amount of malware, or malicious software, originates from there. The government denies it is involved but experts say the high skill level of some attacks suggests the Chinese military, a leader in cyber
