The second day of the Democratic National Convention is likely to be a historic one.
The proceedings began with nominating speeches for Bernie Sanders and Hillary Clinton.
Shyia Nelson, an environmental activist from Vermont,spoke in favor of Sanders' nomination.
"Our revolution continues we will never stop working for a future we believe in," she said. "We will never stop fighting for the change we need and we will never forget the man who leads us."
Clinton's name was entered into nomination by Sen. Barbara Mikulski, one of the first female senators in the country.
"On behalf of all the women. I proudly place Hillary's Clinton's name in nomination to be the next president," Mikulski said to rapturous applause.
The convention then began a roll call vote.
"Are you all ready to make some history?" Baltimore Mayor Stephanie Rawlings Blake asked.
Quiet echoes of the acrimony that marked the first day of the convention were still heard in the arena with some Sanders supporters booing when Clinton was mentioned. But on Tuesday, Clinton supporters were vociferous, easily drowning out the jeers with acclamation.
The roll call is expected to culminate when the delegates officially nominate Hillary Clinton as their party's candidate for president.
Clinton would become the first female presidential candidate of a major U.S. political party.
While the outcome will bring no surprises, Tuesday's proceedings also give Sanders supporters ample opportunity to express displeasure.
That's because the committee will record votes for Clinton and Sanders from all 50 states and territories.
If you remember back in 2008, Clinton called for President Obama to be nominated by acclamation. It was a symbol of party unity after a bruising primary campaign.
Sanders gave a full-throated endorsement of Clinton Monday night, and Tuesday, when speaking to California delegates, he admonished those who would boo Clinton.
"In my view it is easy to boo, but it is harder to look your kids in the face who would be living under a Donald Trump presidency," he told the delegates.
It's still unclear whether Sanders will make a similar gesture Tuesday night.
We'll update this story as the night develops.
