Washington Post reporter Robert Costa is dreading Donald Trump's planned news conference for the one-year anniversary of the Jan. 6 insurrection.

The twice-impeached one-term president announced that he would speak to the media on that anniversary at his Mar-A-Lago resort. Costa told MSNBC's "Morning Joe" that his fellow reporters would not be prepared to call out what would almost certainly be a blizzard of lies.

"I've carefully followed every interview Trump has given since he left office and every rally," Costa said. "Every single time he makes a public appearance, it is the same exact refrain. He gives the lie that the election was a lie and rigged, so you will almost certainly hear this again on Jan. 6, 2022. The challenge for us in the media, for journalists, is to make sure there is context, as this lie is perpetuated by Trump."

"Reporting is needed to not just press the former president on his claims, but to really make sure it is understood, that when he is out there, he is not correct," Costa added. "He's not based in fact when he makes these types of claims."

Even his recent statements in support of vaccines, which drew jeers from his supporters, weren't enough to cover for his attacks on democracy, Costa said.

"How many times during the Trump presidency did people go, 'Oh, today Trump is acting presidential?'" he said. "As a reporter, I follow action. What's he really doing? Every day, even since he made that statement on the vaccine, he's been making public declarations to subvert American democracy. This is his active day-to-day operation ahead of the 2022 and 2024 elections."

"On the vaccine, it's always good to have anyone, whether it's Trump or your next-door neighbor or anybody else, encourage people to be vaccinated, as we have a public health crisis," Costa added. "When it comes to politics, Trump is still Trump."
