Michelle Obama is set to speak Monday at the Democratic National Convention. The first lady, according to several sources, will talk about children on Monday and the role a president plays in the lives of his or her youngsters.

Here’s a quick look at when she will speak tonight and  what she might say.

Why is she speaking?

Michelle Obama is one of the more popular first ladies in recent history. She is loved by a large majority of Democrats and a good number of Republicans, according to a Gallup poll from 2014. Add to that, her relaxed style and pop culture status and you have the perfect makings for a key note speaker.

What will she say?

According to The Washington Post, she will endorse Clinton, saying she believes the former secretary of state has the temperament  and character to be president. She also plans to talk about the role a president plays in a young person's life, The Post reported.

Will she write her own speech?

“The first lady takes a very active role in her speeches,” according to Tina Tchen, the first lady’s chief of staff.

What about the controversy over the Melania Trump speech?

No indication if Mrs. Obama will refer to the fact that Melania Trump’s speech was, in parts, word-for-word her 2008 Democratic National Convention speech, but people will surely be listening to hear if she does.

What time will she speak?

Mrs. Obama is set to take the stage  likely somewhere  around 10:15-10:30 p.m. ET.
