Just days before President Trump was sworn in, his former national security adviser, Michael Flynn, reportedly blocked a military plan opposed by Turkey that was supposed to take aim against an ISIS group.

The plan that he reportedly blocked was to be carried out by Syrian Kurdish forces in Raqqa, a measure Turkey has long opposed.

Flynn, who was fired from his position in February, was registered as a foreign agent for $530,000 worth of lobbying work before Election Day.

"The idea McCarthy would assert this is absurd and false," Matt Sparks told Fox News.
