Story highlights Trump called for the new blueprint to defeat ISIS in Syria and Iraq a month ago

Trump has repeatedly vowed to intensify the fight against ISIS

Washington (CNN) The Pentagon has sent President Donald Trump what it calls a "preliminary framework" for options to ramp up the US battle against ISIS, in a plan he requested in order to make good on his campaign vow to crush the extremist group.

Trump called for the new blueprint to defeat ISIS in Syria and Iraq a month ago, and the document details possible military, diplomatic and financial measures to increase US engagement in the campaign, a US official said.

A "principals committee" of top administration officials will meet Monday afternoon to discuss the way forward in the fight against ISIS. It was not immediately known if Trump would attend the meeting. Defense Secretary James Mattis is scheduled to lead the discussion.

Trump repeatedly vowed during his presidential campaign to intensify the fight against ISIS that began under the Obama administration.
