Donald Trump campaign manager Kellyanne Conway confirmed the news on Sunday.

The campaign did not provide further detail about Melania Trump’s speech, her first since speaking at the Republican National Convention, where she was criticized for cribbing pieces of her speech from Michelle Obama’s in 2008.

Melania Trump generally stays at home in New York to care for her and Donald Trump’s 10-year-old son, but her husband said last week that she would give a couple of speeches before Election Day.

“She is an amazing public speaker,” Trump told ABC. “So she’s agreed to do two or three speeches, and I think it’s going to be big speeches, important speeches. I think it’s going to be great.”
