AKRON, Iowa — Donald Trump Jr. will join U.S. Rep. Steve King for the Republican congressman's annual pheasant hunt in northwest Iowa at the end of this month.

In a Monday tweet, King wrote, "Happy to announce @DonaldTrumpJr will be hunting with us this year at my annual Col. Bud Day Pheasant Hunt on opening weekend of Oct. 28th."

The tweet is in reference to the opening day for Iowa's pheasant hunting season.

The oldest son of President Donald Trump served as a frequent surrogate on his father's presidential campaign, and, along with his brother, Eric, now oversees a trust that included The Trump Organization assets while the elder Trump is president to avert a conflict of interest.

Donald Trump Jr. has come under fire for a revelation earlier this year that he met with a Russian lawyer who promised damaging information about Democratic nominee Hillary Clinton's campaign.

King's pheasant hunt, organized by the congressman's election committee, is named for Col. Bud Day, a Sioux City native and Medal of Honor recipient who was the nation's most highly decorated living service member when he died in July 2013 at age 88. Day and King hunted together periodically.

In the past, King's hunt has attracted a number of high-profile Republican figures. In 2015, he was joined in the field by U.S. Sen. Ted Cruz of Texas, and then-Louisiana Gov. Bobby Jindal, who both at the time were GOP presidential candidates.
