White House senior adviser Ivanka Trump has reportedly been talking with members of Congress about gun legislation in the wake of mass shootings in Ohio and Texas that left 31 people dead earlier this month.

Axios, citing sources familiar with the conversations, reported on Tuesday that President Trump's daughter has been quietly calling lawmakers to get a better understanding on where they stand on reforming gun laws.

She called Sen. Joe Manchin (D-W.Va.) last week while he was vacationing in Hawaii to receive an update on a background checks bill he first introduced in 2013.

"She called Manchin and said she was trying to get a sense of what bills are out there. She had him explain how they drafted the bill, where it stands and what changes needed to be made in order for it to pass," an aide to Manchin told Axios.

The aide added that Ivanka Trump did not address the White House or President Trump's position on gun legislation during their discussion.

President Trump also called Manchin last week and told him he wanted legislation before the Senate returned from recess, The Washington Post reported.

In 2013, Manchin introduced a bipartisan background checks bill with Sen. Pat Toomey (R-Pa.) following a mass shooting at Sandy Hook Elementary School in Newtown, Conn., that left 26 dead, including 20 children. The measure would have required background checks for nearly all firearm purchases.

Ivanka Trump's efforts come as dozens of lawmakers urge Congress to take action on gun legislation after mass shootings in El Paso, Texas, and Dayton, Ohio.

Trump has been outspoken on the issue in recent weeks. She tweeted last week, "Congress should enact Red Flag laws/ Extreme Risk Protection Orders in EVERY state and increase resources dedicated to mental health support."

A White House official told Axios that Trump has been working in concert with the policy and legislative teams on the issue. The White House did not immediately respond to a request for comment from The Hill.

President Trump has called for "intelligent background checks" on gun purchases in the days since the shootings. He's also expressed support for "red flag" laws, which would allow law enforcement to obtain court orders to take away weapons from individuals deemed dangerous or prevent them from buying guns.
