The Washington Post dropped a bombshell report Tuesday about the ongoing investigation into alleged collusion between the Trump campaign and the Russian government in the 2016 presidential election. The report included the fact that special prosecutor Robert Mueller told President Donald Trump's lawyers in March that the president is not a criminal target at this time.

But that does not mean Trump is out of the woods yet, says homeland security expert Juliette Kayyem. According to the Post, Mueller is also preparing a report "on Trump's conduct, particularly as it relates to actions on his part that could constitute obstruction of justice."

Kayyem believes such a report will present evidence of collusion between the Russian government and Trump's campaign.

"I suspect ... that those reports will combine all theories of the case, whether it's money laundering, sex and sex tapes, collusion during the campaign, and obstruction of justice, to create a narrative that one might conclude that the President has been compromised by Russia," Kayyem said. "I know the totality of evidence we've seen so far suggests a campaign that was so intimately captured by the Russians that there's no other conclusion."
