As his second appointment to the Supreme Court begins Senate hearings on Tuesday, dozens of President Trump’s picks for lower federal courts have already been installed, leaving a conservative imprint on the nation’s judiciary.

In particular, the White House has filled the influential circuit court judgeships — the second-highest courts in the U.S. and last stop for many major cases — at a faster pace than his recent predecessors.

More Trump picks to the circuit courts, also known as the U.S. Courts of Appeals, have been confirmed, 26 so far, than any recent president at this point in their first term. Another 13 of the 179 judgeships on the courts are vacant.

Trump’s appointments to the lower district courts have fallen short of all but President Barack Obama, though more than 100 of those positions are available to be filled by Trump-selected judges.
