Former Alaska Gov. Sarah Palin spoke to former President Donald Trump prior to filing paperwork to run for Congress, and Trump encouraged her to do it, two sources familiar with the conversation told Fox News.

Palin announced Friday night that she is seeking the House seat being left vacant by the death of Rep. Don Young, who died earlier this year after serving for 49 years.

"I realize that I have very big shoes to fill, and I plan to honor Rep. Young’s legacy by offering myself up in the name of service to the state he loved and fought for, because I share that passion for Alaska and the United States of America," Palin said in a statement posted to social media platforms.

Friday was the last day that Palin could have entered the race, as it was the deadline for candidates to file for Alaska's June 11 primary. The 2008 GOP vice presidential candidate joins a crowded field that contains more than 40 candidates vying for the seat that was held by Young for nearly half a century.
