Defeated presidential candidate Hillary Clinton told House Democrats on Monday she was sorry she could not deliver the election but encouraged new members to press on in a fight for unity.

Clinton, joined by House Minority Leader Nancy Pelosi, told members on a conference call that she was grateful to have won the popular vote and thanked members in advance for the fights that lay ahead. President-elect Donald Trump, the Republican nominee and billionaire businessman who had never before held elective office, won a decisive victory in the Electoral College.

But the former secretary of State, who lost the 2008 Democratic presidential nomination to Barack Obama, also acknowledged the disappointment.

“No one is sorrier than me,” Clinton told the members. “Heartbreaks don’t heal overnight and this one won’t.”

Clinton said members should not be “discouraged or divided” by the outcome of her political battle with Trump.
