I'd like to challenge your claim about the worst people. African immigrants are more educated, start more private business, and are more law abiding that native-born American citizens. So, I'd like you to qualify how they, the African immigrant in America, are the worst people?
As far as the president telling lies, if we are to take the position he holds, and compare it to others. He hasn't told "some lies" he's told a hell of a lot of them.... and he does so, almost daily. Just the other day, he stated that he wasn't going to the UK, because Obama had made a bad deal in moving the embassy. Well, the first lie is the reason why he wasn't going to the UK. What since does it make to not visit an ally because a previous administration moved an embassy? The second lie, is that it wasn't Obama that made the decision to move the embassy, it was George Bush... but Trump couldn't pass up the chance to attack his predecessor. The thing is, Trump thinks his supporters are stupid. He throws out wild claims, and expects everyone to take it as gospel. Its Amazing the cult of personality the man enjoys.

Perdue cites data on immigrant households benefiting from social welfare programs
Our ruling
Perdue said, "Half of all immigrant households receive benefits from our social welfare system."
Cash assistance for immigrants is very low, about 6 percent, but there are other programs from which immigrants benefit, and Perdue cited benefits broadly. Research from the Center for Immigration Studies found that in 2012, 51 percent of immigrant-headed households (living here legally or illegally) reported to have used at least one welfare program during the year.
That percentage includes a broad definition of welfare, including school lunch. Excluding subsidized school lunches, welfare use for immigrant households would be 46 percent, according to the study.
The study included as welfare beneficiaries immigrant households in which a U.S.-born child is benefitting from a welfare program. Another report from the National Academies of Sciences, Engineering, and Medicine found that 45 percent of immigrant households had food assistance and 46 percent had Medicaid.
Perdue’s statement is accurate but needs clarification or additional information. We rate it Mostly True.
And if you go HERE (linked from within the politifact article) there is extensive tablature, broken down by region and in some cases country. The reality is not as ... pretty ... as you wish to make it seem
