After the killing of a second American journalist, Steven Sotloff, by radical militants, U.S. lawmakers from both major parties say current airstrikes on ISIS targets just aren't doing enough.

This weekend, American airstrikes helped break the monthslong ISIS siege of Amerli in northern Iraq. Last month, U.S. strikes helped prevent a mass killing of an ethnic minority targeted by ISIS and trapped on northern Iraq's Mount Sinjar.
But those strikes are more of an auxiliary to Iraqi operations than a campaign all their own. And the 350 troops the president ordered into Iraq Tuesday night are meant to protect the embassy in Baghdad, not specifically combat ISIS.
Florida Sen. Bill Nelson, a Democrat, now says he's putting forward a bill to give President Barack Obama "clear authority" to expand America's effort against ISIS. Here he is speaking to MSNBC.
FEINSTEIN: "I've learned one thing about this president, and that is he's very cautious — maybe in this instance too cautious."
And Pew Research data shows the number of people saying the U.S. is doing "too little" internationally has almost doubled since last November. Still, opinion is divided. Interestingly, those surveyed named ISIS as America's second-highest security threat, next to Al Qaeda.
For its part, the Obama White House has had a lot of foreign crises to juggle lately.
But it hasn't done a lot to instill confidence in its handling of ISIS.

On Tuesday, when asked about about action on ISIS, a State Department official simply told CNN, "stay tuned."
