Trump in Orlando, via FactBase:

They tried to ruin the family of now-Justice Kavanaugh. They tried to ruin his career, they tried to ruin his life. They even wanted to impeach him on fraudulent charges. Those charges were a fraud. He did nothing wrong. All in pursuit of political domination and control. Just imagine what this angry left-wing mob would do if they were in charge of this country. Imagine if we had a Democrat president and a Democrat congress in 2020. They would shut down your free speech, use the power of the law to punish their opponents, which they're trying to do now anyway, they'll always be trying to shield themselves. They would strip Americans of their constitutional rights while flooding the country with illegal immigrants in the hopes it will expand their political base, and they'll get votes someplace down the future. That's what it's about.[More]

You can watch him say this below:

In a sense, the Democrats have been doing this for years, but under a President Joe Biden it would be as bad as it would have been under a President Hillary, who in 2016 was promising go for what we called the "full Merkel."

And remember, Kamala thinks deporting illegals is an attempt to "remake the demographics of our country".

Let's call this what it is: an attempt to remake the demographics of our country by cracking down on immigrants. That this threat is coming from the President of the United States is deeply reprehensible and an affront to our values. We will fight this. https://t.co/AUShhjLh1H — Kamala Harris (@SenKamalaHarris) June 19, 2019

Trump also said that

The Democrat agenda of open borders is morally reprehensible. It's the greatest betrayal of the American middle class and, frankly, American life. Our country, has a hole, nobody sees anything like it, people are pouring in, but we've stopped them, and now, as I said, we have other people helping us, including the country of Mexico.

Allan Wall covered this in his column today:MEMO FROM MEXICO: Mexico IS Acting, Slowly, In Response To Trump’s Pressure—But He MUST Follow Up.

In reponse to Trump's pressure, Mexico is sending troops to their southern border, presumably with loaded guns, something America's military seems unable or unwilling to do.
