Emanuel has not yet given details of his proposal, but said it was prompted by his frustration with the General Assembly's failure to act, the Chicago Sun-Times reported.
"Waiting is not a strong suit of mine ... I can do certain things in the city. We're gonna take those steps and push to do that ... You'll see [the details] in the coming days," Emanuel promised Thursday.
"I know there's a majority in the state and there's an overwhelming majority in the city for a ban on assault weapons, [high-capacity] clips and comprehensive background checks on all sales, wherever the location may be. And there's also a majority in the Legislature. While they didn't get it done in the [lame-duck] session, their work must begin immediately in this new Legislature for it," he said.
