Jim Geraghty of National Review and Greg Corombos of Radio America are happy to Republicans senators like Ted Cruz, Ben Sasse, and John Kennedy pin down Facebook CEO Mark Zuckerberg on critical issues like censorship, free speech, and user policies that actually benefit Facebook members.  They also react to House Speaker Paul Ryan announcing his retirement, looking both at his record and the increased likelihood that Democrats will take back the House this year.  And they have fun with London's ridiculous new knife control push after 50 stabbing deaths in the city this year, including police confiscating scissors and pliers as deadly weapons.
