Eleven families will fly back to Washington with President Barack Obama on Monday after a speech at the University of Hartford, according to several news reports. 

Sandy Hook Promise, the organization working with the families, declined to confirm the information over the phone, and said a statement will be issued shortly.

The families will be at the University of Hartford Monday where Obama will use his political capital to encourage Congress to pass legislation that would expand background checks for gun purchases.

The families sent a letter to U.S. Senators last week calling for universal background checks, a ban on high-capacity magazines, and reinstatement of the assault weapons ban that expired in 2004.

The Sandy Hook families will speak with lawmakers and encourage their votes. The Senate needs 60 votes to move forward with debate on legislation.

U.S. Sen. Richard Blumenthal said last week that he was optimistic they will get the votes necessary to proceed, but admitted it’s an uphill battle.
