The latest news on the crisis in Ukraine, plus a look at the technology aiding in search for Flight 370.
(CNN) – From the very beginning, China has played a major role in the search for Malaysia Airlines Flight 370.
That made sense, given more than 150 of the 239 passengers on board were Chinese citizens.
But the country's all hands on deck approach hasn't exactly paid off. A New York Times report slams China's role in the search effort, painting officials as being more concerned with showing off their technological capabilities.
Sometimes it backfired on the international stage.
(CNN) – Iran has named a member of the radical student group that seized the U.S. embassy in Tehran and held Americans hostage for more than a year to be its next ambassador to the United Nations.
Echoing former hostages, Democratic Rep. Eliot Engel called the move "a real slap in the face."
Iran's pick is Hamid Aboutalebi, a member of the Muslim Students Following the Imam's Line, the group of militants who seized the U.S. embassy on November 4, 1979, holding 52 Americans hostage for 444 days.
"The Iranians should withdraw their nomination and should send somebody else," said Engel. "All of us that were alive at the time remember that hostage crisis, and that is not something, I think, that we can just turn a blind eye toward."

(CNN) – The disappearance of Malaysia Airlines Flight 370, prompts the need to know what happened to prevent future potential air disasters.
"The first lesson clearly is that we need to be in the position no track air crafts through the entire length of their flights even if it goes outside normal radar coverage," said Tony Tyler, general director of International Air Transport Association, or IATA.
The organization is forming a task force to make recommendations about how to keep track of planes.
IATA's head of corporate communications for the Americas Perry Flint joins "The Lead" to discuss.
(CNN) – The enrollment surge for the Affordable Care Act is more than just a numbers game, it could be President Barack Obama's legacy on the line.
Even Vice President Joe Biden didn't seem to think the administration was going to hit its target of 7 million back in February.
"We may not get to seven, we may get to five or six, and that's a hell of a start," Biden said.
But after a surge on the last day of open enrollment, Obamacare met the original White House target, President Barack Obama said Tuesday at what amounts to a victory for his administration.
So is this a game changer for the White House? And will the new numbers help vulnerable Democrats running for re-election in 2014? CNN chief political analyst Gloria Borger, CNN political commentator and Republican strategist Kevin Madden, and former Ohio Democratic Governor Ted Strickland discuss.
(CNN) – Despite a number of inexplicable setbacks, missteps and flubs related to the search for Malaysia Airlines Flight 370, Malaysian authorities still insist that they wouldn't have done anything differently in this investigation.
On Friday, the search zone abruptly moved again, about 700 miles northeast, when radar revealed the plane likely flew a shorter distance than estimated.
Malaysian authorities admit this latest change only came about when two international teams trying to pinpoint the crash site actually started talking to each other, according to a Wall Street Journal report.
So why weren't they working together before?
Wall Street Journal reporter Jon Ostrower breaks it down for CNN's "The Lead with Jake Tapper."
