Washington (CNN) -- Global financial reform topped the agenda Tuesday as President Obama huddled with Greek Prime Minister George Papandreou, whose country is at the center of Europe's debt crisis. The White House meeting marks the conclusion of a four-country financial relief tour for the beleaguered Greek leader. Beginning Friday, he visited Germany, France and Luxembourg seeking support for his government's new austerity measures to counteract skyrocketing budget deficits. Greece had one of the worst budget deficits in the developed world last year, at 12.7 percent of gross domestic product, more than three times higher than previously declared due to accounting irregularities -- or what some call outright fraud. It also has a public-sector debt equivalent to 113 percent of its entire economy. Athens recently unveiled a package of budget reductions to try to bring its deficit down to the 3 percent level allowed under the rules for the eurozone -- the European Union countries that have adopted the euro currency. Finance ministers from those 16 countries met in Brussels last month to try to find a way to end the crisis that some analysts say could spread to other heavily indebted European nations, such as Portugal, Spain and Italy. Greece's "deficit is more a credibility deficit than a financial deficit, and we need to bring back the sense of credibility," Papandreou said recently. His unpopular budget cutbacks have met with stiff political resistance and strikes at home. Overseas, the Greek prime minister is trying to win support for greater regulation over certain forms of financial speculation that analysts say have made his country's debt crisis worse. Among other things, Papandreou is asking U.S. and other leaders to restrict the use of credit default swaps, which are insurance contracts -- the same kind of contracts that pushed insurance giant American International Group (AIG) to the brink of collapse. Two weeks ago, Fed Chairman Ben Bernanke said the Federal Reserve is looking into actions taken by Goldman Sachs and other Wall Street firms that may have contributed to Greece's debt problems. Bernanke's comment came in response to a question posed by Senate Banking Committee Chairman Christopher Dodd, D-Connecticut, who asked about U.S. banks and hedge funds making financial bets that the Greek government will default on its loans. Goldman Sachs and other banks have been in the news over reports they secretly helped raise $1 billion in credit for Greece in a way that was off the balance sheet, and that they helped hide the country's debt woes from European Union regulators. The New York Times reported recently that some of these same banks also were making side bets that Greece would default on loans it owes American banks and hedge funds. By betting in favor of default, the U.S. banks and hedge funds would win whether Greece pays off its loans or not. Dodd asked whether Bernanke thought there should be limits on the use of these types of bets to prevent firms from creating intentional runs against governments. "The rising price of these contracts contribute to an atmosphere of crisis, making it even more difficult for the Greek government, in my opinion, to borrow," Dodd said. Bernanke noted the similarity of the situation of banks making bets to hedge against Greek debt to banks that made bets to hedge against real estate debt, which imploded AIG. "The poster child for that would be the capital arrangements that banks took out for AIG," he said. "Derivatives have a legitimate purpose, but if they're used to distort accounting results or regulatory ratios, that needs to be addressed." Congress is considering legislation to make such financial bets more transparent. Papandreou has asked American and European authorities to crack down on financial speculators who benefited from taxpayer bailouts only to turn around and profit by exacerbating his country's debt crisis. "Enough is enough," he told an audience at the Brookings Institution on Monday. CNN's Jennifer Liberto, Christine Theodorou and Alan Silverleib contributed to this report.

Mexico City, Mexico (CNN) -- What was Hurricane Karl weakened Friday to a tropical storm after making landfall, but the heavy rain it spawned could still cause mudslides and flash floods in the Mexican interior, forecasters said. Karl was downgraded after coming ashore as a Category 3 hurricane about 10 miles (15 kilometers) north of Veracruz, Mexico, CNN's satellite and radar estimates showed. The storm is forecast to weaken to a tropical depression later Friday or Saturday and dissipate over the mountains of Mexico on Sunday, the U.S. National Hurricane Center said Friday evening. It added the Mexican government has discontinued all coastal watches and warnings. The storm delivered torrents of rain and fierce winds several hours before it hit land around 11:30 a.m. (12:30 p.m. ET). Photographs sent to CNN's iReport by Ricardo Arcaraz, who lives in Veracruz, showed heavy rain and trees on top of power lines. He reported widespread outages. Maximum sustained winds later weakened to around 70 mph (115 kph) with higher gusts, according to the Hurricane Center. Karl, located about 75 miles (115 kilometers) east of Puebla Mexico, was moving west-southwest at about 9 mph (15 kph), it said. Satellite images and surface observations from Mexico suggest Karl is weakening rapidly as it passes through steep mountains, the Hurricane Center added. High winds remain a threat, though forecasters said they will likely weaken too in the coming days. The homes of at least 3,000 families in central Mexico were damaged, the state-run Notimex news agency reported. "Tropical storm force winds are occurring in a small area near the center. These winds will continue to spread inland along the track of the center tonight but should decrease rapidly as Karl weakens," the Hurricane Center said. Potentially dangerous rain also was forecast. "Karl is expected to produce rainfall accumulations of 5 to 10 inches across portions of south-central Mexico, with isolated amounts of 15 inches possible in the mountains," the center said. "These rains could cause life-threatening flash floods and mudslides." Within the past day or so, some 8 inches of rain has fallen in Veracruz, according to CNN meteorologist Brandon Miller. Some local flooding was already reported, the Mexican Interior Ministry said. Officials closed some roads and urged evacuations for large, low-lying areas in Veracruz. Mexico's National System for Civil Protection issued a red alert, the highest level, for central and southern Veracruz. An orange alert was in place for northern Veracruz and the states of Hidalgo, Tlaxcala and Puebla. A yellow alert was issued for the states of Tamaulipas, San Luis Potosi and Oaxaca. Mexican President Felipe Calderon also sent a warning Friday morning on his Twitter account. "An alert for Hurricane Karl in the nation's central states," it said, adding that Karl "could convert to a Category 4. It will enter through Veracruz around midday." Texas could be spared any major problems because a storm surge occurs only near the landfall location, said CNN meteorologist Sean Morris. Coastal flood advisories have been issued for south Texas, which means forecasters expect a small amount of coastal flooding but nothing serious, Morris said. A larger threat to south Texas will come from several inches of rain that could cause flooding and mudslides. The area could see as much as 4 inches by Sunday, with isolated amounts of up to 6 inches in far southern Texas. CNN meteorologists Brandon Miller and Mari Ramos contributed to this report.

LONDON, England (CNN) -- London commuters crammed onto buses, scrambled for taxis, cycled or simply walked on Wednesday as a strike by Tube workers shut down most of the subway network. Commuters queue for packed buses in London on Wednesday morning. The strike began Tuesday at 7 p.m. (2 p.m. ET) but the first full effects were felt during Wednesday's morning commute. The strike was set to last for 48 hours with a normal service resuming Friday morning, according to Transport for London (TfL), which runs the city's transportation network. The RMT trade union called the strike after talks with management over pay, job cuts, and disciplinary issues broke down. "RMT doesn't resort to industrial action lightly," General Secretary Bob Crow said in a statement. "The fact is that Tube workers have been driven into walking out today." Transport Commissioner Peter Hardy said the talks had been making progress on all issues and he urged the RMT to return to the table. "The RMT leadership says we were close to a deal," Hardy said in a statement. "If that is the case, then they should call off the strike, return to talks ... and resolve this issue without any more disruption to Londoners." TfL was running extra buses and free shuttle services across the River Thames during the strike. Electronic travel cards used for the TfL network were temporarily being allowed on all train lines in greater London, it said. While most services on the Tube were shut because of the strike, one line -- the Northern line -- was running normally and five others were running on a reduced schedule, TfL said. "It's been really good," a girl on Oxford Street told CNN about her commute. "The Northern line is running perfectly." Still, some bus services were packed with commuters who normally ride the underground trains or who failed to find a taxi. "I think we'd all like to strike for more money, but unfortunately we can't," said one woman at Oxford Circus, where the Tube is closed. Others hit the pavement and walked. "It's OK -- quite refreshing," said a man on Regent Street. He said he had just walked from Liverpool Street Station, a train station as well as a Tube stop that is more than 2.5 miles away. The RMT represents about half of the 20,000 employees on the Tube, a TfL spokeswoman said. Other unions including Unite and TSSA represent the rest, she said, and were not on strike.
