Ivanka Trump is feeling grateful.
Hours after her father, Donald Trump, was elected the 45th president of the United States early Wednesday morning, the future first daughter took to her Instagram to express her thanks to the American people.
Ivanka shared a smiling photo of the whole Trump family on stage at the president-elect’s Election Night event at the New York Hilton Midtown in New York City.
“Thank you, America, for the trust that you placed in my father. He will never let you down!” she captioned the photo.
The 35-year-old mother of three was spotted out in New York City earlier Wednesday.
“It’s back to business for the entire Trump family already — they never stopped and barely slept,” a source tells PEOPLE of the Trump family.

Trump delivered his victory speech from Midtown Manhattan just after 2:30 a.m. — with Ivanka, Donald Jr., 38, Eric, 32, Tiffany, 23, and Barron, 10, as well as several grandchildren and wife Melania by his side.
Veteran Republican campaign adviser Lou Midkiff, who works closely with Trump’s vice presidential pick, Indiana Gov. Mike Pence, told PEOPLE that “we went to sleep at 5 [a.m.] and woke up at 8 [a.m.],” adding, “we’re on cloud nine.”
