​Former President Donald Trump made a surprise appearance at a campaign event for Sarah Huckabee Sanders, his former press secretary and current Republican candidate for governor in Arkansas.

Sanders on Sunday tweeted a photo of her and Trump.

​”​Great weekend on the campaign trail featuring a surprise appearance at one of my events by President Trump!​” she said in the post. 

​​It’s unclear when or where the campaign event was held. ​

Sanders served as the White House spokeswoman, replacing Sean Spicer, until 2019.

Trump endorsed her run for governor in January, calling her a “warrior who will always fight for the people of Arkansas.”

“Sarah is strong on Borders, tough on Crime, and fully supports the Second Amendment and our great law enforcement officers,” Trump said​ in a statement​. “She loves our Military and Veterans – and her home state of Arkansas. Sarah will be a GREAT Governor, and she has my Complete and Total Endorsement.”​

Sanders, whose father, Mike Huckabee, was Arkansas governor between 1996 and 2007, replied in another tweet.

“Thank you President Trump for your endorsement and for always believing in me. As governor I will defend our freedom and lead with heart,” she said.​

Since leaving the White House on Jan. 20, Trump has been staying at his Mar-a-Lago resort in Florida, where he hosts Republican lawmakers and endorses GOP candidates.

Over the weekend, he teased his daughter-in-law Lara Trump’s potential run for the Senate in North Carolina in 2022.

“I didn’t exactly prepare for this, but I was walking by, and I heard everybody screaming,” Trump said in his impromptu remarks at a fundraiser for Big Dog Ranch Rescue. “I want to thank Lara, who has been so incredible — and I don’t know, are you running for the Senate? I hear she’s going to run for the Senate!”​

Lara Trump is married to Trump’s son Eric Trump. ​
