David Plouffe, White House senior adviser, sent a fiery memo to House and Senate Democrats late Friday urging them to use the August recess to echo President Barack Obama’s message to middle-class families that “he is on their side by fighting for legislation that grows the economy from the middle out, not the top down.”

“The President and Democrats in Congress move into the August recess with clear momentum on the question of who to trust on taxes and, more broadly, whose economic agenda will benefit the middle class,” Plouffe wrote in the memo obtained by POLITICO. “Over the coming weeks, there is an opportunity to build on this momentum and shape the legislative agenda this fall by highlighting the choice Congress faces at this make-or-break moment for the middle class.”
