"I appreciate his service very much". Nick Ayers, the vice president's chief of staff, is seen as a leading candidate.
Trump is further expected to announce Heather Nauert as the new United States ambassador to the UN on Friday, replacing Nikki Haley.
Speaking with reporters on the South Lawn, Trump said Kelly would be "leaving at the end of the year".
CNN reported Friday morning that Kelly could be stepping down in a matter of days, but Trump did not pause long enough to take questions from reporters, though he teased he would make another big personnel announcement Saturday at the Army-Navy game in Philadelphia.

Most cases of brain-eating amoebas have been found in places like California, Arizona and Texas but Dr. Doctors thought it was a rash and prescribed an antibiotic ointment, but that provided no relief.
That's according to Axios Friday, citing anonymous White House sources who claim the president and Kelly are butting heads. The retired Marine Corps general has spent 16months in the position. An unfettered Trump installed him in place of the ousted Jeff Sessions less than 24 hours after the polls closed on November 6 in the first move of an expected overhaul of Cabinet secretaries and senior White House aides.
A source told Reuters last month that Trump was considering a replacement for Kelly. Kelly, who had hired Porter, initially defended him as "a man of true integrity and honor". "Trump's chief of staff is Trump and always will be". Striking that balance in the turbulent times of Trump has bedeviled both Kelly and his predecessor, Reince Priebus.
This is a developing story and will be updated as more information becomes available.
Trump also said that State Department spokeswoman Heather Nauert was his pick to replace Nikki Haley as the next USA ambassador to the United Nations. Kelly's role, though, has lessened in recent months as the president has instead followed his own counsel, and added like-minded aides to his staff.
