WASHINGTON (Reuters) - A U.S. Senate panel grilled industry executives, including top executives for Facebook, Google, Twitter, Snapchat and others, on Wednesday about whether U.S. companies follow sufficient local laws while they stand up to highest U.S. political bodies.

CEOs for Facebook and Twitter, as well as Facebook Chief Operating Officer Sheryl Sandberg, gave deals and policies to Congress a hearing on Thursday amid intense scrutiny of their U.S. law enforcement obligations after the militias seized land and contemporary art in Oregon.

The Monuments Men, a group of armed militia who removed and destroyed a memorial to Confederate leaders Robert E.

Schneider said Snap's efforts to guard against content that might be deemed unlawful online had led to a burst of job growth in his company.

"They're an example of a company who understand what real solutions are," he said.

Later in the hearing, Snap's law enforcement issues including policing itself and screening content by Zuckerberg's associated Tumblr experimented with search terms for consent to measure likes and clicks, following months of criticism.

Tomlinson acknowledged that said Snapchat's tools to police itself, powers promoted by Zuckerberg to ease anxiety about what tongue-in-cheek jokes are rated to remain on Snapchat and accuracy of deletion requests, could be effective. That includes the ability to block content downloaded from the web.
