US Representative Edward J. Markey, a Democratic Senate candidate who has maintained a limited public profile since Monday's Boston attacks, said President Obama's visit for an interfaith service on Thursday will "help to bring the beginning of the closure to this incident."
Markey, who like the other Senate hopefuls suspended his campaign on Monday, said on MSNBC's "Morning Joe" that the campaigns had "all agreed from the minute that this occurred" to cease active electioneering.
"We're going to do it until, really, there is an appropriate moment where we can begin campaigning, but after the period of grieving," Markey said.
Both the Senate and Boston mayoral campaigns have gone into freeze mode since the attacks, although candidates have preserved varying degrees of visibility.
Markey's Democratic rival, US Representative Stephen F. Lynch, has appeared frequently at press conferences. Lynch represents much of Boston, and is friendly with the family of Martin Richard, the 8-year-old boy killed Monday on Boylston Street.
One of Monday's victims, 29-year-old Krystle Campbell, lived in Markey's district.
Obama is scheduled to speak at Thursday's 11 a.m. interfaith service at the Cathedral of the Holy Cross in the South End.
