The White House is hosting a roundtable on sanctuary cities Tuesday afternoon with the President, Attorney General Jeff Sessions, Secretary Kirstjen Nielsen of the Department of Homeland Security, Republican lawmakers and others, Axios has learned.

Why it matters: Conservatives tried to use this week’s massive government spending bill to cut federal funds from sanctuary cities, but they failed, according to sources involved in the process. But Trump officials want to use Tuesday’s event to highlight the issue and put pressure on cities that don't comply with federal immigration law enforcement.

The roundtable guest list:

Donald Trump

Mike Pence

John Kelly

Stephen Miller

Attorney General Jeff Sessions

DHS Secretary Kirstjen Nielsen

ICE acting Director Tom Homan

Gene Hamilton, Counselor to the Attorney General

Rep. Michael McCaul (R-TX)

Rep. Martha McSally (R-AZ)

Rep. Mark Meadows (R-NC)

Sen. Pat Toomey (R-PA)

Sen. Tom Cotton (R-AR)

Texas AG Ken Paxton (R-TX)

Arkansas AG Leslie Rutledge

Members of the law enforcement community

Big picture: The Department of Justice is already suing the state of California for the state’s “radical” sanctuary cities law. And In his speech on Monday, President Trump blamed sanctuary cities for releasing criminals, drug dealers and gang members back into society, claiming that "ending sanctuary cities is crucial to stopping the drug addiction crisis."

Flashback: Last month, Oakland Mayor Libby Schaaf warned residents of an incoming ICE raid. This infuriated ICE officials and Jeff Sessions.
