Former Secretary of State Hillary Clinton will provide the keynote address Wednesday at the state Democratic convention, New York Democrats announced Monday.

Clinton, a former U.S. senator representing New York, will also endorse Gov. Andrew Cuomo for a third term as he faces a Democratic primary challenge from actress and education advocate Cynthia Nixon.

“New York has led the way in fighting back against the divisive, hateful agenda of the ultra-conservatives in Washington and worked to create a fairer, more inclusive state for all,” Clinton said in a statement. “Working together we will elect more Democrats every level of government to advance our shared progressive vision of equality and opportunity, and build a brighter future for generations to come.”

Clinton’s appearance at the convention is sure to rile Nixon’s supporters, many of whom are aligned with Clinton’s rival for the Democratic nomination for president in 2016, Bernie Sanders. Nixon herself endorsed Clinton in the campaign.

The appearance is the most high-profile one for Clinton in political circles since her loss to President Donald Trump.
