This legislation is the most significant immigration enforcement and border security related bill to pass the Senate in nearly three decades.

The bill will be considered by the U.S. House of Representatives this week before heading to President Trump to be signed into law.

Deporting millions of migrants or enforcing the Laken Riley Act will largely depend on Congress' ability to allocate roughly $100 billion.

The House voted 263 to 156 to approve the Laken Riley act, sending the measure to Trump for his signature. The measure would make it easier for federal immigration officials to detain and deport those without legal status who are charged with specific crimes.

The bill would allow Immigration and Customs Enforcement agents to arrest and detain undocumented immigrants accused of theft-related crimes.

Under the bill, called the Laken Riley Act, state attorneys general like Ken Paxton would have the ability to challenge federal immigration officials.

The U.S. Congress on Wednesday delivered Republican President Donald Trump legislation requiring the detention of immigrants living in the U.S. illegally who are accused of theft, with a significant number of Democrats voting in favor.

The House cleared legislation Wednesday that would impose stricter penalties on undocumented immigrants who commit crimes in the United States, sending the first bill of this Congress to President Donald Trump in his second administration.
