Fiscal cliff: Obama calls Dimon, Buffett

As part of efforts to pressure Congress to support his approach, the president has invited business, labor and civic leaders and non-profit groups to the White House to press his case. His re-election was expected to give him some leverage in the negotiations.

Dimon said last month that it was terrible policy to let the fiscal cliff deadline draw so near before beginning talks. He also said he would be willing to see his tax rate rise if it meant avoiding any economic shock.

Dimon and the other executives could not immediately be reached for comment.
