(CNN) - U.S. House Speaker Nancy Pelosi says President Bush should consider boycotting the opening ceremony of the Olympics Games in Beijing this summer to protest China's human rights record.

"I think boycotting the opening ceremony, which really gives respect to the Chinese government, is something that should be kept on the table," Pelosi told "Good Morning America" co-anchor Robin Roberts in an interview to air Tuesday morning, according to the ABC News Web site. "I think the president might want to rethink this later, depending on what other heads of state do."

Pelosi said she does not think U.S. athletes should boycott the games themselves.

(CNN) - Nearly 79,000 Pennsylvanians registered as Democrats last Monday, the state's deadline for those looking to participate in the April 22 primary.

A near-majority of the Pennsylvania electorate is now registered Democratic - just over 4 million of the greater than 8 million voters in the state. Fewer than 2 in 5 are Republican.

The one-day registration total includes more than 33,000 new voters and nearly 46,000 Republicans and independents who switched their registration, according to reports released Monday by the Pennsylvania Secretary of State.

By comparison, around 7,800 Pennsylvanians became Republicans last week, including 6,000 new registrants and roughly 1,800 party-switchers.

PARIS (CNN) - Six French aid workers convicted of plotting to kidnap African children for adoption in Europe have been released from prison following their pardon by Chad's president, according to the French Justice Ministry.

The workers from the international charity Zoe's Ark and a Chadian middleman were arrested in October and sentenced to eight years in prison. Under an agreement between Chad and France, the French aid workers were allowed to serve their time in a French jail.

Chadian President Idriss Deby pardoned the seven convicts Monday, state radio announced.

WASHINGTON (CNN) - Lawmakers have returned to Washington after a two-week break vowing to confront the deepening mortgage crisis. But despite the increasing pressure to find solutions to the problem, Senate leaders find themselves locked in a procedural stalemate over how to take up a stalled homeowner relief bill.

Negotiations are expected to continue right up to a key vote planned Tuesday afternoon on the Democratic-authored bill, aides on both sides said.

The bill would, for the first time, allow bankruptcy judges to reset mortgages on primary residences. It would also provide $4 billion for local communities to buy and refurbish foreclosed properties; provide $200 million for counseling to help homeowners avoid foreclosure; give tax breaks for the home building industry; and improve loan disclosure and transparency.

Republicans are threatening to block the bill, as they did before the recess, unless Democrats give in to their demands to allow votes on certain GOP amendments.

WASHINGTON (CNN) - Michigan Rep. Bart Stupak proposed a plan Monday that would apportion his state's delegates to the Democrats' national convention by taking into account both the results of the state's January primary and the total popular vote of all primary contests nationwide.

In a proposal sent to Democratic National Committee Chairman Howard Dean, and to candidates Sen. Hillary Clinton and Sen. Barack Obama, Stupak proposed allotting 83 of Michigan's pledged delegates based on the January vote, and splitting the state's remaining pledged delegates and superdelegates - 73 total - based on the nationwide vote.

The DNC punished Michigan because it went against party rules. Under Stupak's proposal, Clinton would receive 47 delegates while Obama would be awarded 36. The rest would be divided according to the nationwide popular vote total after all the primaries are completed.

WASHINGTON (CNN) - A weapons policy expert at the U.S. Defense Department pleaded guilty on Monday to an espionage charge involving disclosing national defense information to China, federal officials said.

William Bergersen, 51, of Alexandria, Virginia, was arrested in February and charged with conspiracy to illegally disclose national defense information to unauthorized individuals.

Bergersen was a weapons systems policy analyst at the Defense Security Cooperation Agency, a DOD agency located in Arlington, Virginia.

(CNN) - Coalition forces found the remains of a U.S. soldier missing in Iraq for nearly four years after a local Iraqi tipped them off, military officials said Monday.

The location, which was not disclosed, was searched March 20, according to a statement from Multi-National Corps. Officials positively identified Staff Sgt. Keith Matthew Maupin through DNA testing on Monday - the same day they notified the soldier's family.

A U.S. Army official told CNN that fragments of a U.S. military uniform found with the remains raised immediate suspicions that the remains were those of Maupin, who was a 20-year-old private first class in the Army Reserves at the time of his capture. He was captured wearing an Army field uniform that has not been used by the military in more recent years.

 WASHINGTON (CNN) - Federal safety officials negligently approved work plans for a Utah coal mine that collapsed in August 2007, leaving nine dead, a Labor Department report concluded Monday.

The report does not reach conclusions about the cause of the disaster at the Crandall Canyon mine, which killed six miners and three would-be rescuers. But it found that officials of the federal Mine Safety and Health Administration could not demonstrate that it did "everything appropriate" to protect workers in approving a plan for the risky mining technique used at the site.

In a written response, MSHA chief Richard Stickler objected to the use of the term "negligent" and any suggestion that mine operator Murray Energy had pressured the agency into approving the use of what is known as "retreat mining" at Crandall Canyon. Stickler wrote that auditors were unable to back up those implications in their report.
