President Donald Trump warned Tennessee voters against allowing “radical Democrats” to turn back economic recovery in America, in rally for Republican candidate Marsha Blackburn in Chattanooga yesterday.

Blackburn is hoping to keep retiring Senator Bob Corker’s seat in Republican hands. A Fox News poll released last week showed her with a nine-point lead over Democratic former Governor Phil Bredesen.

Trump started his speech at the Blackburn rally by cheering the country’s economic recovery through his leadership, noting “we are over-performing.”

He asked his supporters if they wanted “the resistance” to take it all away.

“We have the hottest economy on earth,” noting more than 157 million Americans now have a job. “There is an electricity in the air. We are breaking every record in the history of our country.”

He called the Democrats the party of erasing borders and championing socialism, “the liberal agenda of high taxes and high crimes.”

He said America has the worst immigration laws, and “the world laughs at us.”

Four caravans are currently traveling inside Mexico, totaling some 12,000 Central American migrants.

“That’s an invasion. I don’t care what they say,” Trump said to cheers. He received similar applause when promoting the economy, unemployment numbers and judicial appointments.

Singer Lee Greenwood’s hit “God Bless the USA” has been a standard at Trump’s events ever since he announced his campaign for president.

For Trump’s rally in Chattanooga, Greenwood appeared on stage to deliver the song in person.
