NEW YORK, March 22 (Reuters) - JPMorgan (JPM.N) Chief Executive Jamie Dimon is scheduled to meet with Lael Brainard, the director of the White House's National Economic Council, during the executive's planned trip to Washington, according to a person familiar with the situation. The CEOs of major banks gathered in Washington for a two-day scheduled meeting which started on Tuesday, sources familiar with the matter previously said. The quarterly meeting of the Financial Services Forum included Dimon and Bank of America Corp (BAC.N) CEO Brian Moynihan, who head the nation's two largest lenders, the sources said. The banks were aiming to work out details for what needs to be done for First Republic within the coming 24 hours, another source said. Eleven lenders, including the eight members of the Financial Services Forum, threw First Republic a lifeline of a combined $30 billion in deposits last week.
