(CNN) President Donald Trump signed an executive order Thursday meant to allow churches and other religious organizations to become more active politically, though the actual implications of the document appeared limited. The order, which Trump inked during a ceremony in the White House Rose Garden, directs the IRS not to take "adverse action" against churches and other tax-exempt religious organizations participating in political activity that stops short of an endorsement of a candidate for office. But pastors are already free to deliver political speeches, and regularly do. Churches and other tax-exempt organizations are restricted from endorsing or explicitly opposing political candidates under the 1954 Johnson Amendment, but the executive order Trump signed Thursday makes clear that those activities would still not be permitted.It is the policy of the Trump administration "to protect and vigorously promote religious liberty"The order will direct the IRS to exercise "maximum enforcement discretion"
