WASHINGTON – First lady Melania Trump's communication director Stephanie Grisham will be the new White House press secretary, replacing Sarah Sanders.

President Donald Trump said he offered the job to Grisham on Tuesday morning, and she accepted.

“A lot of people wanted the job – a lot of people wanted to do it," Trump said from the Oval Office. "So many people said, ‘Stephanie.’ She’s here. She knows everyone. I think she’s going to do a great job.”

The announcement was first made by Melania Trump, who wrote on Twitter that she could "think of no better person to serve the Administration & our country."

Grisham, who also serves as the first lady's deputy chief of staff, will become President Trump's third press secretary in three years . Sanders is leaving the position at the end of the month and will return to her home state of Arkansas.

Sanders tweeted her congratulations to Grisham and said she "is going to do an incredible job."

"I’m sad to leave the WH, but happy that our team is in such good hands," Sanders wrote. "I’m so proud that another mom and a great friend will be taking over. The President and the country are lucky to have her!"

In addition to the role of spokeswoman, Grisham will serve as White House communication director, a job previously held by Bill Shine, who resigned in March after less than a year on the job.

Grisham has a long history with the Trump family and is known for her loyalty to them, particularly the first lady.

She worked as an aide in Trump’s presidential campaign in 2016 and is one of the few campaign staffers still in the White House. After Trump was elected, she went to the White House to work as a deputy to Trump’s first press secretary, Sean Spicer.

Grisham went to work for the first lady in March 2017, serving first as communication director and then as deputy chief of staff.
