Meet The Press aired less than 24 hours ago, that's where he said this.
TL;DR: Trump's quote there happened after Tarrio's conviction.
Full context:
KRISTEN WELKER:
Let’s talk about potential pardons because a lot of your supporters are wondering about that. Proud Boys leader Enrique Tarrio was sentenced to 22 years in jail. Now that you know what the sentence is, 22 years in jail, will you give him a pardon?
FMR. PRES. DONALD TRUMP:
Are you ready?
KRISTEN WELKER:
Will you give other Proud Boys a pardon?
FMR. PRES. DONALD TRUMP:
I don’t know him. I never met him. I never heard of him until I started reading this stuff.
KRISTEN WELKER:
Will you pardon him?
FMR. PRES. DONALD TRUMP:
But I want to tell you: He and other people have been treated horribly. Antifa killed people, and those guys didn’t even get tried in many cases.
KRISTEN WELKER:
There’s no evidence Antifa was there.
FMR. PRES. DONALD TRUMP:
They put these guys in jail for 17, 18, and 22 years. They didn’t kill anybody. Some of them never even went into the Capitol. Some of them weren’t even in D.C. And they got a 22- or a 17-year sentence. 16, 18, 15, 22.
KRISTEN WELKER:
Well, more than 1,000 people have been charged, Mr. President.
FMR. PRES. DONALD TRUMP:
Wait a minute. Wait a minute. Yeah. 1,000 people. How many people — let me ask you this. How many people were charged for destroying Portland? How many people were charged for burning down the police precinct and the courthouse in Minneapolis?
KRISTEN WELKER:
Will you give him a pardon? Will you pardon him, though? Will you pardon him?
FMR. PRES. DONALD TRUMP:
I’d certainly look at it. I’d look at that. And I’d look at all the other people that have suffered, the J6 people.
KRISTEN WELKER:
Mr. President, let me ask one final question --
FMR. PRES. DONALD TRUMP:
People — people that went there.
KRISTEN WELKER:
– and let’s move on to foreign policy.
FMR. PRES. DONALD TRUMP:
That didn’t even go into the building have suffered gravely. And you have to say one system of justice, right? You take a look at what’s gone on in Portland. They burned down the city. The city is in shambles to this day. The store owners don’t even rebuild storefronts anymore. They put up two-by-fours.
KRISTEN WELKER:
I want to move on to foreign policy, Mr. President.
FMR. PRES. DONALD TRUMP:
But why do you do that?
KRISTEN WELKER:
Let me just ask you one more question.
FMR. PRES. DONALD TRUMP:
Why do you give me a horrible question and then you don’t let me answer it? You’re off to a bad start, I’m telling you.
KRISTEN WELKER:
Mr. President, I just — I want to make sure we get to talk about foreign policy as well.
FMR. PRES. DONALD TRUMP:
No, but I don’t mind. I have all the time in the world.
KRISTEN WELKER:
You do? Okay.
FMR. PRES. DONALD TRUMP:
I have all the time in the world. Why is it that the people, Antifa people, and very bad people, that burned down Portland, burned down Minneapolis, burned down so much — and New York City, what they did in New York City — and they were barely charged? And, yet, the people in Washington in some cases never even went into the building. They’ve been persecuted. They’ve been persecuted.
KRISTEN WELKER:
Well, the people who were charged on January 6th, some of them were charged with sedition. Some of them were charged for violating the Capitol —
**FMR. PRES. DONALD TRUMP:
And we’ll take a look at everything. But many of these people have been persecuted, what they’ve done to them.**
KRISTEN WELKER:
They — your supporters? Your supporters, you’re talking about?
FMR. PRES. DONALD TRUMP:
And they didn’t do this to the people that burned down — you take a look at Portland. It’s like a burned-down hulk of a city, including the federal courthouse.
KRISTEN WELKER:
Mr. President, if you were re-elected, would you pardon yourself?
