CNN's Kaitlan Collins attempted to corner the Trump White House during Thursday's press briefing, questioning why no criminal charges have been filed if the evidence President Donald Trump is expected to discuss in his speech is as significant as the administration has suggested.

White House Press Secretary Karoline Leavitt fired a clear warning shot, telling CNN's Kaitlan Collins that the evidence has not even been fully declassified yet and that Americans will see it for themselves tonight.

CNN's Kaitlan Collins: "Regarding the president's speech tonight, he's been in office over 540 days now. If what he says tonight is backed up by evidence, why hasn't anyone been charged?"

Press Sec. Karoline Leavitt: "He hasn't revealed it yet. He hasn't declassified the documents yet and you will see what he says tonight and then we'll move forward appropriately from there."
