WORCESTER - Former President Bill Clinton is heading to Worcester Monday for a late night rally in support of Hillary Clinton as she works gain more momentum in her primary bid.

U.S. Representative Congressman James P. McGovern, D-Worcester, said a location for the rally is still yet to be determined, but confirmed the rally will be sometime after 11 p.m. in Worcester.

"He wanted to know if it was ok if he came, even if it was late," McGovern said. "I said, 'We'd love you to come at any time'."

Hillary Clinton, who just won the South Carolina Democratic primary over Vermont Sen. Bernie Sanders, will head to Springfield and Boston Monday as part of her presidential campaign. The visits occur one day before people will head to the polls and vote in the Massachusetts presidential primary.

Sanders campaigned in Boston and Amherst last week.

McGovern said the former president expressed interest in coming to Worcester, a city Bill Clinton has visited in the past while supporting gubernatorial candidate Martha Coakley. He has also stopped in Worcester to support McGovern and U.S. Sen. Edward Markey.

Bill Clinton was in Worcester after the Worcester Cold Storage & Warehouse fire that took the life of six Worcester firefighters in December 1999.

"I think the president loves Worcester and obviously Massachusetts has been a state that Bernie has been in for a while and it looks it has tightened up," McGovern said. "The Clintons are not taking anything or anyone for granted."

McGovern said he was knocking on doors in Central Massachusetts Saturday. He will be at Cafe Reyes on Shrewsbury Street in Worcester with New Jersey Sen. Cory Booker Monday to support Hillary Clinton's campaign. The event begins at 10 a.m.

McGovern said a recent poll showing Hillary Clinton slightly ahead over Sanders in Massachusetts shows momentum is building on her side.
