Trump is skipping the National Rifle Association’s (NRA) annual convention this weekend, his second snub in as many years of an organization long seen as a key political ally for Republicans.

The move marks his second consecutive absence from the NRA’s annual meeting — held this year on April 16-19 in Houston, Texas — after attending every convention since 2015.

While the prominent gun rights group has largely brushed off Trump’s decision to skip the event as a scheduling issue, some critics say it underscores the NRA’s waning influence in Washington after years of financial and legal turmoil.
