President Bush reportedly will intervene in the West Coast port lockout Monday with a board of inquiry.
By one estimate, the lockout, which has entered a second week, is costing the American economy $2 billion a day.
The board is to make an assessment of the economic damage of the labor dispute and determine whether the two sides are negotiating in good faith, media reports said.
Talks between workers and managers broke down late Sunday, after the union rejected the latest contract proposal. The dispute has shut down 29 West Coast ports.
