President Obama has invited the Senate Democratic caucus to the White House on Wednesday evening, according to a White House official.
The meeting will come less than two weeks ahead of the president's State of the Union address and amid negotiations in the upper chamber over an extension of emergency unemployment benefits.
It also comes less than 48 hours before Obama is expected to announce his proposed reforms to the nation's national security program, following a comprehensive White House review of controversial surveillance programs.
The president is also likely to hear from some Senate Democrats who have been pushing new legislation imposing additional sanctions on Iran. More than a dozen Democratic senators, including Sen. Charles Schumer (D-N.Y.) and Foreign Relations Committee Chairman Robert Menendez (D-N.J.), have backed the bill, which would impose penalties on banks and companies that help Iran export more oil and blacklist certain Iranian industries, if Tehran does not agree to a comprehensive nuclear agreement within the next six months.
Over the weekend, Obama said in a statement he would veto that legislation, adding that the bill endangered negotiations with Iran.
"Unprecedented sanctions and tough diplomacy helped to bring Iran to the negotiating table, and I'm grateful to our partners in Congress who share our goal of preventing Iran from acquiring a nuclear weapon," Obama said. "Imposing additional sanctions now will only risk derailing our efforts to resolve this issue peacefully, and I will veto any legislation enacting new sanctions during the negotiation."
