Vice President Biden was at a White House meeting last month to discuss  gun violence.

The White House, seeking more police support for its push to toughen gun laws, announced Thursday that Vice President Biden would hold a roundtable session about gun safety with law enforcement officials next week.

Biden will travel to Philadelphia to meet with law enforcement officials and congressional Democrats on Monday, on the eve of President Obama's "State of the Union" address on Tuesday. In his address, the president is expected to detail his ambitious second-term legislative agenda, which includes sweeping gun-control measures.
