Washington (CNN) Rep. Alexandria Ocasio-Cortez and White House counselor Kellyanne Conway sparred Sunday over the congresswoman's Twitter silence following the Easter Sunday church bombings in Sri Lanka, with Ocasio-Cortez saying Conway used the attention around her lack of tweets "as an excuse to stoke suspicion" about her faith.

Appearing on CNN's "State of the Union" Sunday morning, Conway told host Jake Tapper that Ocasio-Cortez, a New York Democrat, tweeted "many times" about the shootings at two New Zealand mosques last month that left 50 dead, but "never once" tweeted about the series of church bombings in Sri Lanka last week that left more than 250 people dead and hundreds injured on Easter Sunday.

In a handful of tweets about Conway's comments , Ocasio-Cortez, whose use of Twitter has become one of her trademark characteristics, defended the fact that she did not post a tweet about last week's attacks, noting in one tweet that she had been on a technology hiatus while she was visiting her grandmother in Puerto Rico.

You are using this as an excuse to stoke suspicion around my Christianity + faith life, @KellyannePolls.



The Sri Lanka massacre was horrifying. No one should be targeted for their religion.



If you're so moved, let's do more to welcome immigrants fleeing religious persecution. — Alexandria Ocasio-Cortez (@AOC) April 28, 2019

"Are you trying to imply that I am less Christian? What was the point of you bringing this up on national TV?" Ocasio-Cortez asked Conway in the tweet.

In a separate tweet, Ocasio-Cortez wrote that the "terrorist attack in Sri Lanka was horrifying," before saying in another that Conway was "using this as an excuse to stoke suspicion around my Christianity + faith life."
