President Donald Trump's border wall was strengthened as the fist-pumping leader soars in polls.

Troops from the 1st Combat Engineer Battalion, 1st Marine Division, mounted barbed fencing along the southern border wall near San Ysidro, San Diego, from February 7 to 17.

The effort, in collaboration with U.S. Northern Command and the Department of Homeland Security, aims to strengthen security and reduce illegal crossings by adding more physical barriers.

On Monday, February 24, Sergeant Major Carlos Ruiz of the Marine Corps inspected the area.

Local media reported yesterday that Trump had gained new supporters following mass deportations, cuts to what the government considers wasteful federal spending, and new policies.

A Trump tracking poll shows his approval rating has increased by one point in the past two weeks, now at 54 per cent. Respondents claimed that he kept his word during the campaign.

His popularity has been further boosted after kicking 'corrupt and disrespectful' Ukranian leader Volodymyr Zelensky out of the White House and stopping military support to the country.

Trump, known for his hardline nationalist and anti-immigrant rhetoric, has promised a sweeping crackdown on undocumented and illegal immigrants in the country.

On his first day of office, he declared a 'national emergency' at the southern border with Mexico.

He has also issued a memo telling the U.S. Agency for International Development to adopt an 'America First' policy, threatening sanctions on staff who refuse to obey.

Dozens of deportation flights have also taken off, sending illegals back to their homeland in handcuffs.

In contrast to the bid to oust illegals, Trump is vying to replace them with millionaires who will buy 5 million USD 'gold cards' to gain residency and citizenship.

On Sunday, he said: 'We should spend less time worrying about Putin, and more time worrying about migrant rape gangs, drug lords, murderers, and people from mental institutions entering our Country - So that we don't end up like Europe!'
