WASHINGTON (AP) – Supreme Court nominee Amy Coney Barrett has declined to say whether she views the criminalizing of in vitro fertilization as constitutional, describing it as an abstract question. The appeals court judge nominated by President Donald Trump to join the nation’s highest court signed a 2006 statement opposing “abortion on demand.” That statement was then circulated by a group in her home state of Indiana that has also criticized IVF. While the statement Barrett signed didn’t address IVF, Democratic Sen. Tammy Duckworth of Illinois has urged her colleagues to reject Barrett’s nomination, citing her daughter’s conception using the common reproductive technology.
