President Barack Obama said he was in Connecticut to offer the love and prayers of the entire nation, adding that he struggled to find the words that could comfort those in Newtown.

It was the fourth since his election that Obama has had to visit a community deep in grief as a result of mass violence.

There are reports that he privately told Connecticut Governor Dan Malloy that it had been the worst day of his presidency.

Although he acknowledged that words could not match the depths of their sorrow, he did his best to provide comfort.

“I am very mindful that mere words cannot match the depths of your sorrow, nor can they heal your wounded hearts,” Obama said.

After sharing in the grief, Obama noted that many of us are parents, saying this incident needed to inspire change.

“We can’t tolerate this anymore, these tragedies must end, and to end them we must change,” Obama said.

President Bill Clinton signed an assault weapons ban into law in 1994, however that measure ended in 2004. Sen. Dianne Feinstein wants that measure renewed, saying she will introduce a bill doing just that.
