A prayer vigil and rally is scheduled to begin at noon at the Federal Reserve at 101 Market St. today, calling for solutions to widespread foreclosures. Rev. Jesse Jackson, who is currently on a national tour promoting his nonprofit RainbowPUSH Coalition's campaign for mortgage relief for homeowners facing foreclosure, is scheduled to appear. Jackson and other religious and community leaders are putting pressure on lenders to restructure loans in order to avoid foreclosures.
