Good morning, and welcome to the US politics live blog.
Barely a week after sweeping to a stunning midterm victory, Democrats have found themselves facing an altogether different battle, one within their own ranks.
Maryland Senator Chris Van Hollen has launched a challenge to Chuck Schumer, of New York, for the SenateâÂÂs top Democratic leadership post. Announcing his decision during an interview with MS Now last night, Van Hollen argued that last weekâÂÂs midterm election results showed Americans wanted a fundamental change in Washington, and that Democrats needed new leadership in order to deliver that.

He said:
We saw a huge outburst of democracy on election day â red states, blue states, purple states â and it wasnâÂÂt only a rejection of Donald Trump and his corruption, his wars and his cruelty, it was also about a call for a larger change, to take on a broken economic system thatâÂÂs rigged in favour of the very wealthy against working people, and itâÂÂs fuelled by a corrupt political system.
The call was to reject the status quo and to reject business as usual, and to do that, I think we need new leadership.âÂÂ
His challenge came just days after Democrats secured control of the Senate, winning at least 55 seats in what has been a remarkable election cycle for the party. Winning the leadership contest requires a majority of the caucus, about 28 or 29 senators, with an election scheduled for next month.
The caucus votes behind closed doors by secret ballot, but Van Hollen told MS Now that he had the support of âÂÂmore than 10â Democratic senators.
Progressive heavyweight Bernie Sanders, an independent senator from Vermont who caucuses with the Democrats, has already publicly declared he will not support Schumer, saying âÂÂthe time is now for changeâÂÂ. Endorsing Van Hollen, Sanders said: âÂÂThe American people voted for change. They want a Democratic Party that will stand up to powerful special interests, take on the billionaire class and fight for working families.âÂÂ
Incoming Democratic senator Abdul El-Sayed, of Michigan, has also openly backed Van Hollen, saying he was âÂÂproud to stand with him in his bid to lead our Senate majorityâÂÂ.
The American public spoke clearly last week. They rejected Trumpism. But we have yet to earn our mandate. That will require bold leadership. I called [Van Hollen] to lead our caucus as a candidate back in April because he leads with courage and experience. We need both right now.âÂÂ
Responding to Van HollenâÂÂs leadership bid, Schumer, who has led Senate Democrats since January 2017, said he welcomed âÂÂa discussion about the future of our caucus and the important work aheadâÂÂ, but that he had the votes to be re-elected as leader.
