President Donald Trump said Friday he would seek sweeping changes to U.S. immigration policy through an executive order, suggesting he might create a ¡°road to citizenship¡± for certain migrants brought to the country illegally as children and shift the criteria for new arrivals to a ¡°merit-based¡± system.

The new effort will be unveiled ¡°over the next four weeks,¡± Trump said in an interview with Telemundo.

Critics ¡ª including high-profile members of the president¡¯s own party ¡ª immediately questioned whether he has the legal authority to overhaul immigration laws without passing legislation through Congress.
