Hope Hicks, the White House communications director and one of President Trump’s longest-serving advisers, said Wednesday that she was resigning. Some reports state that Trump demanded her resignation.

The 29-year-old has been with Trump from the beginning. She joined his 2016 presidential campaign with no political experience, but was known to be well-organized and good with communication. She had a unique understanding of the president’s personality and style.

According to reports, Hicks had been considering leaving for several months with pressure mounting for her resignation in the White House. She told colleagues that she had accomplished what she felt she could with a job that made her one of the most powerful people in Washington.

Her resignation came only one day after she testified for eight hours before the House Intelligence Committee. She apparently told the panel that on the job she occasionally told white lies, but never told lies about Russia’s influence in the election.

The president released a statement saying: “Hope is outstanding and has done great work for the last three years. She is as smart and thoughtful as they come, a truly great person. I will miss having her by my side, but when she approached me about pursuing other opportunities, I totally understood. I am sure we will work together again in the future.”

Hope was known to be able to stabilize people who worked closely with the president, even when they were at odds with each other. During the duration of her job, she had a low profile.
