Sarah Sanders' book is coming shortly before the 2020 election

St. Martin’s Press will announce Thursday that former White House press secretary Sarah Sanders will publish a memoir about her Trump administration experiences in fall 2020 — right before the election.

Why it matters: Sanders, who could be combative with reporters and is seriously considering a run for Arkansas governor in 2022, will be a high-profile supporter of President Trump's re-election.

Sanders, a Fox News contributor, lives in Little Rock.

• She says in a release out later today:

"From Arkansas to the White House and back, I'm excited to tell my story about the challenges of being a working mom at the highest level of American politics, and my role in the historic fight raging between the Trump administration and its critics for the future of our country."
