Over the weekend Lebanon President Michel Suleiman's six-year term expired but the parliament failed to select a new leader. Lawmakers are worried about the leadership vacuum as the country deals with a surge of refugees from neighboring Syria, which is involved in a civil war.

“I urge all parties to engage in constructive dialogue to ensure that a deeper political crisis can be averted,” said Kaine, who serves on the Senate Foreign Relations Committee. “2014 is an important year for Lebanese democracy and I implore all parties to further incubate the culture of dialogue and compromise that is vital to Lebanon’s political future.”

Lebanon's government system requires that the president be Christian while the prime minister is a Sunni Muslim and the parliament speaker is a Shiite Muslim as part of a power-sharing deal. The reason the parliament has failed to pick a new leader is because lawmakers influenced by the Islamic group Hezbollah have boycotted the process.
