Nancy Pelosi urged Democrats to prepare for a doomsday scenario where the 50 state House delegations would decide a stalemate between Joe Biden and Donald Trump.
What some Democrats are not preparing for, however, are the confirmation hearings of Supreme Court pick Amy Coney Barret, with at least four Senators indicating they would boycott proceedings.
Ms Pelosi was in full campaign mode on Monday as she also hit the president on The New York Times tax return story, saying his $421m in debt to come due in the next four years made the president a "national security threat".
While Pelosi focused on the president's debt, the Biden campaign focused on the $750 taxes reportedly paid with a new attack ad and website launched in less than 24 hours of the story going live on Sunday, and a website, "Trump Tax Calculator", launched within less than 24 hours.
Biden refused Trump's suggestion of a drug test before the first presidential debate with a graphic riposte, with his campaign saying "If the president thinks his best case is made in urine, he can have at it".
While their campaigns were making pee jokes, the candidates were deep in debate prep, with reports that Biden was bracing for Trump to 'weaponize' corruption claims against Hunter Biden for his business dealings in Ukraine.
Elsewhere, Cindy McCain - widow of former Republican presidential candidate John McCain, joined Biden's transition advisory board as the Democrats prepare to take office if winning in November.
