Eric Fehrnstrom, the Romney adviser typically most prolific on Twitter and often the first to respond through the medium to Axelrod, has not tweeted since Friday.
Both campaigns cancelled appearances in response to the Colorado movie theater shooting that happened early on Friday last week. A dozen people were killed and many more injured. Obama visited the Denver suburb over the weekend to comfort the community, a move Romney praised. Both campaigns pulled negative ads from the state following the incident.
Both campaigns have events scheduled on Monday as they ease back into the campaign.
