Melania Trump will sit with relatives of people that have been killed by undocumented immigrants during Donald Trump’s joint address to Congress.

The White House announced the six special guests, who will be seated with the First Lady during the address, due to take place later today.

Among them, Jessica Davis and Susan Oliver are the windows of Detective Michael Davis and Deputy Sheriff Danny Oliver, who were California police officers and were killed on duty by an undocumented immigrant in 2014.

The two officers have a bill named after them, which is aimed to increase cooperation between federal and local officials to enforce immigration laws.

Jamiel Shaw Sr, whose son Jamiel Jr was 17-years-old when he was shot by a gang member in 2008, also appears on the Trumps’ guest list. The White House says Jamiel’s killer was also an illegal immigrant.

The choice of guests seems to reflect the US President’s crackdown on people living in the US illegally. The American Action Forum, a centre-right public policy institute, estimated the cost of deportations could rank up to half-a-trillion dollars.

This comes as a growing number of Democrats are reported to bring young undocumented immigrants as their guest to Mr Trump’s prime-time address to Congress, The Hill reports. The legislators hope to make a point over the US President’s immigration policies so far.

The widow of the late Supreme Court Justice Antonin Scalia is also expected to attend the event. Earlier this month, President Trump nominated Judge Neil Gorsuch to succeed Justice Scalia, who died in February 2016, on the Supreme Court.
