Former Vice President Joe Biden is stepping up his political game in a new attack on President Trump aimed at raising cash to help Democrats take control of the House and Senate in 2018 while raising his profile for a potential presidential bid in 2020.

In a new note to supporters about "our president," Biden portrayed Trump as a president that has abandoned the helpless in Puerto Rico and stood for Nazis.

Joe Biden's book is to be released in November.

"Folks, it's up to us now to do what our president has not: Uphold America's values. Defend our constitution. Say, full-throated and together, ‘This is not who we are,'" said Biden.

The attack came as Biden is preparing for his American Promise book tour and promotion of his new group.

The American Promise website said it is raising money for 2018 candidates, potentially making it an influential PAC.

In his note, Biden listed his problems with Trump:

Today, we have an American president who tweets about NFL ratings while 3.4 million American citizens face a desperate search for food and water in Puerto Rico.

We have an American president who has publicly proclaimed a moral equivalency between Neo-Nazis and those who would oppose their venom and hate. Who has emboldened white supremacists with messages of comfort and support.

A president who cares more about dismantling his predecessors' achievements than ensuring tens of millions of Americans know the security of health insurance -- one who threatens our global standing on a weekly basis with his careless actions and his words.

Every week, it's something new. And I know it's tempting to throw your hands up -- to give up, shut down, or tune out for the next three years. But we cannot grow weary. We cannot grow discouraged. And we cannot give an inch.
