Why Joe Biden can't just pass gun laws as Matthew McConaughey

President Joe Biden will struggle to enact stricter gun laws in the US, despite a passionate

speech at the White House by Oscar-winner Matthew McConaughey following the brutal school shooting in Texas

Actor Matthew McConaughey gave a passionate and tearful speech at the White

House as he pleaded for new restrictions on guns following the brutal massacre of children in Texas.

The Texas native spoke of the heartbreak of families after 21 people were killed, 19 of them

young children, when killer Salvador Ramos walked into a school in Uvalde, Texas on May 24 and opened fire.

Despite frequent gun killings - over 700 people in the US have been killed since the Uvalde massacre last month

presidents have failed to introduce widespread restrictions on guns, and Joe Biden is finding it difficult to introduce legislation due to pushback.

US gun laws mean that weapons including deadly AR-15 assault rifles are often easily accessed in many states and are frequently used in mass killings.
