Arrests on the U.S.-Mexico border are not showing any signs of slowing down in the first weeks of the Biden presidency.
Border Patrol says more than 75,000 migrants were detained in January.
That's 4,000 more than the month before.
Officials blame that on an increase in crime and instability in some countries.
Some migrants have what officials call inaccurate perceptions that immigration and border policies are changing.
Border Patrol adds that the January number may be overstated because some migrants may have been arrested more than once.
