U.S. Rep. Adam Kinzinger, who also is a pilot with the Wisconsin Air National Guard, was deployed to the U.S.-Mexico border earlier this week.
The Channahon Republican, who also is a lieutenant colonel, will stay within the United States, as he has with previous border missions, according to a press release issued by his office.
"As always our Washington D.C. and Illinois offices will continue to serve the people of the 16th District and keep the Congressman updated while he serves his mission along our southern border," said Communicatons Director Maura Gillespie in a press statement.
Kinzinger told the Chicago Sun-Times he has had a couple meetings with President Donald Trump to talk about national security issues, noting the two have talked about Syria and Afghanistan.
According to the Sun-Times report, Kinzinger has flown border duty before, three times under former President Barack Obama, doing immigration and drug-smuggling aerial surveillance.
Kinzinger, whose district includes Ottawa and Streator, has said he is in favor of building a border wall between the U.S. and Mexico, but he also has spoken out against federal government shutdowns.
