ERIE, United States, Sept 29, 2024 (AFP) - Donald Trump on Sunday used a

speech in key swing state Pennsylvania to urge a "violent" police crackdown
on crime in the United States and repeated his new insult for Kamala Harris,
calling her mentally disabled.

Pennsylvania is considered the most important of the seven toss-up states
that will likely decide the balance in November 5's presidential election.

Harris, the Democratic candidate, was due to address supporters in another
battleground, Nevada, later Sunday.

Republican candidate Trump, who held a similar rally in swing state Wisconsin
on Saturday, reprised his dark, racially charged message about an America
crumbling under "invasion" by violent migrants and other criminals.

Recounting isolated -- but widely publicized -- incidents of thieves staging
brazen daylight robberies of shops in major cities, Trump got a loud cheer
when he said police should become "extraordinarily rough."

Criminals, he said, "have to be taught" and this could be done "if you had
one really violent day."

"One rough hour -- and I mean real rough -- the word would get out and it
would end immediately," Trump said.

"The police aren't allowed to do their job" because "the liberal left won't
let them."

As on Saturday in Wisconsin, Trump spent much of his speech painting a
picture of a failing United States, inundated by what he said was the
"massive number of savage criminal aliens that Kamala Harris has allowed to
invade."

He claimed "terrorists are pouring into our country" and cited "a big prison
in the Congo, in Africa," as the source of "a lot of people" last week.

Anti-immigrant sentiment has been at the core of Trump's appeal in
economically depressed, majority-white parts of the country ever since his
2016 presidential victory, but the rhetoric is turning ever more extreme as
election day nears.

Following record numbers of illegal border crossings earlier in President Joe
Biden's administration, a tightening of rules -- to the consternation of
immigrant rights and civil liberties groups -- led to a plunge in numbers
this year.

Crime, including murder, is also in steep decline nationwide, the FBI says.

Trump has long prided himself on his ability to coin insulting nicknames or
slurs for his opponents and on Sunday he repeated one that he aired on
Saturday, calling former top California prosecutor and current Vice President
Harris "mentally impaired."

"Crooked Joe Biden became mentally impaired. Sad. But lying Kamala Harris,
honestly, I believe she was born that way," Trump said to loud laughter from
the crowd.
