This is not the first time Trump has used trade as a border tool.

which → impose → Mexico
That tariff expired July 24.
asserted
tariff → expire → ?
Other tools remain in play.
asserted
tools → remain → play
The ruling did not touch Section 232 national security tariffs on goods such as steel, aluminum and autos, and Treasury Secretary Scott Bessent said combining the remaining authorities would leave 2026 tariff revenue "virtually unchanged."
asserted
combining → touch → revenue
Trump's post did not say which tariffs would be doubled or under what law.
asserted
tariffs → say → law
Border states are also shifting.
asserted
states → shift → ?
Trump's post said Texas' incoming Democratic governor had been informed, and Texas Attorney General-elect Nathan Johnson, a Democrat, could drop the state's defense of SB4, the law allowing state arrests for illegal border crossings.
