Updated 4:40 p.m. | Reps. Edward J. Markey and Stephen F. Lynch have suspended all campaign activity following the explosions at the Boston Marathon on Monday.
In a single-sentence statement, the Markey campaign stated it had suspended "campaign activities including canvassing, phone banking, fundraising and television advertisements."
The Lynch campaign released a statement on the news, then confirmed to CQ Roll Call that it, too, has halted campaign activities.
Lynch released a statement Monday in reaction to the events.
"I am terribly saddened by today’s news," Lynch said. "Right now we need to let the trained emergency personnel do their jobs to ensure that there are no other threats, and that we can get a better sense of what happened. No matter who or what is responsible, this is a terrible tragedy for our city and our nation. Our thoughts and prayers are with those who have been injured today."
