DETROIT (AP) — General Motors and Chrysler asked the government for an additional $14 billion in aid, a dramatic acknowledgment that conditions in the U.S. auto industry have grown significantly worse in just two months.

GM presented a survival plan that also calls for cutting a total of 47,000 jobs globally and closing five more U.S. factories. That represents the largest work force reduction announced by a U.S. company in the economic downturn. Chrysler said it will cut 3,000 more jobs and stop producing three vehicle models.

Meanwhile, the United Auto Workers union said it has reached a tentative agreement with Chrysler, GM and Ford Motor Co. on modifications to labor contracts. Such concessions were also a condition of the government bailout.

DETROIT (AP) — Ken Cockrel Jr. became the city's new mayor Friday, vaulted into office by a sex scandal that destroyed the reign of Kwame Kilpatrick and threw Detroit's government into chaos for months.

Cockrel, who was president of the City Council, took the oath of office Wednesday, but the change didn't take effect until 12:01 a.m. Friday. A public ceremony was scheduled for later Friday.

Cockrel has hired a former federal prosecutor as deputy mayor, picked a police chief and urged residents to put their trust in the new team at City Hall.

In remarks to reporters this week, he said getting his hands on the city's budget problems is a priority. Cockrel already has met with outside auditors.

DETROIT (AP) — A judge ordered Mayor Kwame Kilpatrick to jail Thursday for violating the terms of his bond in his perjury case, a decision the judge said he would have made for any "John Six-Pack" defendant before him.

The mayor, who is accused of lying under oath in a civil case and faces eight felony counts, made a trip across the Detroit river to Windsor, Ontario, on city business last month without informing the court in advance, leading the county prosecutor's office to request Kilpatrick be punished.

Only minutes earlier, the mayor offered an apology to the court, telling District Court Judge Ronald Giles that for seven months, "I've been living in an incredible state of pressure and scrutiny."
