Fox News reports that “President Obama and military leaders are weighing a host of factors as they consider expanding airstrikes into Syria, including the Assad regime’s demand to seek permission first and warnings that the strikes could trigger ISIS retaliation.”  

“But they soon could face another complication: Congress.”  

“With Congress set to return early next month, influential lawmakers from both sides of the aisle have urged the administration to seek an up-or-down vote on military action in the region.”
