Some cited "job restrictions" while another said he was wary of the press.
"Give us your tired and your oppressed and we'll divide you from your children", he said of Trump's policies.
US President Donald Trump and his wife, Melania, have been being greeted with pomp and circumstance, along with protesters, as they arrived at Blenheim Palace for a gala dinner with British PM Theresa May.
Asked about the President's view on US-UK relations, he said: "He has worked here for so many years, he knows so many people". "It's really kind of irrelevant to what we're trying to do, and doesn't express the opinion of the British people that I've met", he told the BBC's Today programme.
"I've been reading a lot about Brexit over the last couple of days and it seems to be turning a little bit differently where they're getting at least partially involved back with the European Union", he told reporters.

"And I said Putin may be the easiest of them all", he continued. The first lady will remain in London on Friday when protests are set to take place. In fact, during past visits, both Barack Obama and George W. Bush spent a night at Buckingham Palace, and although the latter also did not receive a warm reception in London, he nonetheless made sure to make several stops during a 2003 visit.
The Facebook event page for the protest, states that participants will "defend diversity", and show solidarity for other marginalised groups, including people of colour and transgender people.
Shrugging off the plans for mass protests, which on Friday will include a giant baby-shaped blimp bearing Trump's features, he said in Brussels: "They like me a lot in the UK".
Mr Batten said: "What mayor of a city would insult the president of a country which is an ally, even if they don't like that president".
She added: "They will be talking to teams on the ground and they will be liaising with police services up and down the country".
"I think whenever his detractors go after him, it makes him double down and it actually encourages him to keep going and prove everybody wrong", she said.
