The martial law that they are talking about is "Congressional Martial Law".
Under the martial law procedure, longstanding House rules that require at least one day between the unveiling of significant legislation and the House floor vote on that legislation — so that Members can learn what they are being asked to vote on — are swept away. Instead, under “martial law,” the Leadership can file legislation with tens or hundreds of pages of fine print and move immediately to debate and votes on it, before Members of Congress, the media, or the public have an opportunity to understand fully what provisions have been altered or inserted into the legislation behind closed doors. This is the procedure that the Leadership intends to use to muscle through "the important bills" in the next few days.
