A weak monthly U.S. jobs report could spell trouble for President Barack Obama and shift momentum to Mitt Romney, the presumptive Republican presidential nominee, AP reported. The Labor Department said Friday U.S. employers added only 80,000 jobs in June - a third straight month of weak hiring - leaving the unemployment rate unchanged at 8.2 percent. The economy has added just 75,000 jobs a month in the April-June quarter. That's one-third of 226,000 a month created in the first quarter. Job creation is also trailing last year's pace through the first six months of 2012. Romney immediately sought to take advantage of the report, taking time out from his vacation in the northeastern state of New Hampshire, to attack Obama's handling of the economy. -- SPA
