Illinois Sen. Mark Kirk met with a group of family members of some of the students killed at Sandy Hook Elementary School on Wednesday.
The meeting lasted 45 minutes and included six adults and 1 child. Kirk was reportedly "quite moved' by the meeting, and was seen wearing a Newtown pin and wristband given to him by the group, NBC 5's Mary Ann Ahern reported.
The meeting was held in conjunction with Sandy Hook Promise, a Newtown, Conn.-based group dedicated to finding solutions for gun violence.
It came on the same day a bipartisan bill that would expand background checks is being discussed in the Senate. According to one of the bill's proponents, Sen. Joe Manchin, D-W.Va., it's not expected to receive enough votes to pass.
NBC News reports that the bill was 4 to 5 votes short, a gulf that could widen if Democrats in conservative states decide not to support the measure.
Kirk has been a strong supporter of the bill, and has met with the parents of slain Chicago teenager Hadiya Pendleton, and Chicago mothers Annette Holt and Pam Bosley, who both have lost their teenage sons to gun violence.
Public support appears to be waning for stricter gun laws, with a recent AP-GfK poll showing 49 percent of respondents in favor of cracking down and 38 percent saying they should stay the same.
