SIOUX CITY -- U.S. Rep. Steve King, R-Kiron, on Friday said he still plans to sue President Barack Obama over an administration change that would result in fewer deportations of illegal immigrants. King said he expects to file legal paperwork by Labor Day.
"(Obama) is acting in a lawless manner," said King, who has been a frequent critic of U.S. immigration policy.
King said he wishes the lawsuit would proceed more quickly, but he is working on which entities and people will join as plaintiffs in the suit. He is also mulling which U.S. Circuit Court is most appropriate for the suit.
King said he plans to hold a press conference fully announcing the lawsuit particulars prior to Labor Day.
The administration on June 15 announced that people under age 30 who came to the U.S. by age 16, who pose no criminal or security threat, who were successful students or served in the military can get a two-year deferral from deportation. The change will also allow those meeting the requirements to apply for work permits.
That same day, King said he planned to file a lawsuit.
On Friday, King said his opposition stands, and he believes President Obama has exceeded constitutional authority.
King has experience with high-profile lawsuits.
He successfully sued then-Iowa Gov. Tom Vilsack, a Democrat, over an executive order in 1999 that banned discrimination against gay, lesbian and transgender government employees.

King will file lawsuit against president by Labor Day
