correspondent karl cameron has our report. >> i'm back. reporter: a highly choreographed hearing included a photo op of it on the president and first lady who welcomed the clintons the day before by questioning their positions. he complained that the democratic party has become too centrist and without venturing clinton, clinton tried to tamp down the white house speculation quickly. >> it is true that i am thinking about it. >> before today, that is not why i am here. >> the independent super pac for hillary was already out in force. she kept her partisanship broad and focused on the midterms. >> a choice between the guardians of gridlock in the champions of shared opportunities and shared prosperity. reporter: are summerlong book to her got attention. she outlined the administration's foreign policy is not to do stupid things and none of that have come up. vermont senator bernie sanders has been threatening to run for this event for years and he is an independent and turned his iowa visit to correspond with clintons without naming her, h

david cameron slapping penalties on airlines if they don't comply. cnns karlis live in london. clearly, david cameron, clearly officials in the uk are really concerned about the 500 britains they say who recollects have gone to wage jihad. >> absolutely. that is front and center of the proposals mr. cameron made to parliament. he was putting more meat on the bone telling us exactly how he proposed to go about this. that is why he's talking about greater powers for the police to seize passports to stop people heading off to fight jihad or join groups like isis. he's talking about pushing through tighter no-fly lists like you have in the u.s. to stop suspects boarding planes so they can't head off to trouble spots. also, perhaps one of the most radical new proposals that still has to be debated by parliament is the suggestion that britain could block its own citizens from returning to the country if they are found to have been in war zones at the time. now, some of these measures would be involve certain secret powers by the intelligence service, the so-called c
