WASHINGTON - Treasury Secretary Henry Paulson said Friday that the Bush administration will move ahead with a plan to buy stock in financial institutions.

Paulson said the program to purchase stock in financial institutions will be open to a broad array of institutions.

The administration received the authority to make direct purchases of stock in banks in the $700 billion measure Congress passed last week to rescue the nation's financial system.

It would mark the first time the government has taken equity ownership in banks in this manner since a similar program was employed during the Great Depression.

Paulson said the administration was moving forward with the program during a news conference at the conclusion of discussions among finance officials of the Group of Seven major industrialized countries. That group endorsed the outlines of a sweeping program to combat the worst global credit crisis in decades.
