President Obama will sit down with Senate Democrats on Wednesday as both political parties spar over a plan to fund the federal government.

White House press secretary Jay Carney confirmed that Obama would huddle with representatives of the caucus "to discuss obvious matters."

The meeting comes as Republicans in Congress increased their pressure on Obama to get directly involved in the negotiations over a spending bill to fund the government through September.

“Where is the president?” Majority Leader Eric Cantor (R-Va.) repeatedly asked in a press conference Wednesday morning.

The Senate is expected to hold test votes on a Democratic and Republican spending proposals on Wednesday, both of which are expected to fail. Both sides are still locked in a stalemate over a longer-term plan.

Obama last week named Vice President Joe Biden to lead a team of White House officials to help hammer out an agreement. But Republicans have criticized the choice, citing Biden's current overseas trip to Europe.

Carney said Biden is making calls to congressional leaders from Moscow, where he is meeting with top officials.
