NEWTOWN, Conn. -- President Barack Obama will visit Newtown Sunday evening to meet with victims' families of the Sandy Hook Elementary School shootings, the White House announced Saturday night.

Jay Carney, White House Press Secretary, said "Tomorrow evening the president will travel to Newtown to meet with the families of those who were lost and thank first responders. The president will also speak at an interfaith vigil for families of the victims as well as families from Sandy Hook Elementary scheduled for 7 p.m.

The event is closed to the public and open only for families of victims. The president will not make any public appearances in Newtown, according to the White House.

Obama's visit to Newtown for an interfaith vigil would be the fourth time he has traveled to a city after a mass shooting.

Hours after the shootings that killed 27 people, including 20 children,, a tearful Obama said he grieved first as a father. In those remarks and later in his Saturday radio address, Obama called for "meaningful action" to prevent such shootings, but did not say what it should be.

The president had planned to travel to Maine on Wednesday for an event promoting his positions in "fiscal cliff" negotiations, but the White House canceled that trip because of the shooting.

Danbury Mayor Mark Boughton Tweeted earlier Saturday that helicopters people heard over Danbury today were an advance team setting up for a possible presidential visit.

It is expected that major roads will be blocked and access restricted while Obama is in town.

The last time Obama visited Connecticut was on Aug. 6 when he attended separate fundraisers at the Stamford Marriott Hotel & Spa and at the Westport home of Hollywood producer and studio executive Harvey Weinstein.
