Now it's possible I'll hear that and say hey I'm changing my mind.
Trump said "I would certainly prefer" not to fire Rosenstein, but he did not make a commitment one way or another before meeting with him face-to-face.
"There's no obstruction except for the fact that I fight back, if you call that obstruction", he said.
Rosenstein, of course, has come under scrutiny after the New York Times report last week saying that he talked about secretly recording Trump and getting Cabinet members to invoke the 25th amendment.
President Donald Trump speaks during a news conference, Wednesday, Sept. 26, 2018, in NY. Gly asked what, specifically, Trump's administration would do to support Kurdish people in Iraq and Syria as the Islamic State threat waned.
Rosenstein will be meeting with President Trump directly on Thursday, after which, well, anything can happen.
After Attorney General Jeff Sessions recused himself from special counsel Robert Mueller's investigation into potential ties between Russian Federation and the Trump campaign, Rosenstein took over supervision of the investigation.

Tanya Ferry, environment manager at the Port of London Authority which is monitoring the whale, said it was unclear what the whale could eat.
"I don't want to do anything that gets in the way of this very important Supreme Court pick", Trump said.
Rosenstein appointed Mueller in May 2017, oversees his work and has repeatedly defended the breadth and scope of the probe.
Trump scheduled the meeting with Rosenstein to discuss his professional fate - and perhaps the future of the investigation into Russia's election interference in 2016.
Even if Rosenstein survives the week, it's not clear how much longer he'll be around.
Allies such as Fox News host Sean Hannity have accused the Federal Bureau of Investigation of leaking the damaging information on Rosenstein in the hope that Trump would fire him, setting off another firestorm just weeks before elections that will determine political control of Congress. Trump has signalled that he may fire Sessions after the midterms, and Rosenstein could go with him.
